Oil Changes and Maintenance Schedules

There are two Jeep Patriot Maintenance schedules, depending on your driving conditions. Almost everyone I know falls into schedule "B" (see criteria below).

That means you should change your oil every 5000 km (3000 miles). In the real world you can probably stretch this out a bit, especially if you are using a 5W-30 synthetic such as Mobil 1 or Pennzoil Platinum.

Under no conditions should you try to stretch things beyond 10,000 km (6,000 miles). In that case you would be exceeding both schedule "B" and the more relaxed schedule "A" for less harsh driving conditions.

Schedule “B”. It is for vehicles that are operated under the conditions that are listed below and at the beginning of the schedule.

  • Day or night temperatures are below 0° C (32° F)
  • Stop and go driving
  • Extensive engine idling
  • Driving in dusty conditions
  • Short trips of less than 16 km (10 miles)
  • More than 50% of your driving is at sustained high speeds during hot weather, above 32° C (90° F)
  • Trailer towing
  • Taxi, police, or delivery service (commercial service)
  • Off-road or desert operation
  • Heavy loading
NOTE: If ANY of these apply to you then change your engine oil every 5 000 km (3,000 miles) or 3 months, whichever comes first and follow schedule “B”.

NOTE: If ANY of these apply to you then change your coolant every 170 000 km (102,000 miles) or 60 months, whichever comes first and follow schedule “B”.

NOTE: Under no circumstances should oil change intervals exceed 10 000 km (6,000 miles) or 6 months whichever comes first.

CAUTION: Failure to perform the required maintenance items may result in damage to the vehicle.

Hi I have the same message, my pat have 8300km, I changed the oil when 5,000km, can I just reset the message? (the level indicator is fine (safe), or it is necessary to change it?

It is too expensive going to the Jeep service, I want to change it myself, what brand of oil is recomended? 5W-30 synthetic?


thanks
 
#19 ·
Too Expensive? How much is your dealer charging you? Mine gave me a contract for four oil changes with the filter and oil for 32 dollars. 8 per oil change. It also works with any dealership in the country. That is a lot cheaper than doing it yourself.

I thought the Pat took 5W-20 oil?

I drive 100 miles a day, at least. I change every 3,000 miles, and use conventional oil.

Stop and go, highway, idle, and off road are normal for me.
 
#4 ·
There is no "conventional" 5w-20 that I know of. They all use at least a partially synthetic base stock. (i.e. on top of the additives)

To quote someone else on this forum, "you are poking a hornets nest" when you mention 5w-20 being the only weight option. We will have to leave it to you to search the forums and make your own decision.

I always use a synthetic 5w-30, however it may or may not be the best choice.
 
#6 ·
How accurate is the oil change indicator? Should I change the oil every 3,000 miles or only when the indicator says to?
 
#7 ·
The indicator does a "best guess" based on a conventional oil, RPM, distance and driver habits. It cannot test or evaluate the condition of your oil.

The safe answer is every 5000 km. In the real world if you use a synthetic you can go to 10,000 km with no issue I am sure. I use 5w-30 Mobil 1 EP and go to 8,000 km.

There are several right answers to your question, that I am sure of.
 
#9 ·
It is in the Owners Manual.

  1. You put the key in the ignition
  2. Turn to the key to power on the accessories (but do not start the engine)
  3. Immediately after doing so press down and release the accelerator pedal 3x

Try once or twice if it does not work the first time.

Mobil 1 5-20W are available now at (US) Walmart for around $23.00 for 5Q. It is a very good deal. I just did my (early) 1 year oil change (1 year May15), as it has just over 21,000Km. I provided the oil & filter, the Jeep dealer changed $26 + Tax, and did a recall notice on the sunroof.
Did the first oil change back when the Pat was at 5,000Km. IMHO, using Mobil 1 and just doing regular daily driving & under 20,000km/12,000miles, you should be good for every 12 months oil change. But do check your dip stick on a regular basis.
 
#16 ·
Yea, most everyone had the first oil change occur early. Mine was at 2700 miles, but it now goes off every 5500-5800 miles. (I just changed it last night as a matter of fact, 5 qts of Valvoline SynBlend 5w-30 and a Purolator Pure One filter, 19.99 at Advance Auto).

Change the oil, then follow the instructions in the posts above to reset the light.
 
#17 ·
for right now, till the warranty is up.. i ll stick with the recommended
service intervals..every 6,000 miles..

afterwards i ll change over to Royal Purple..read a review in 4x4 magazine that synthetics really do their best over 10,000 miles..
 
#18 ·
My oil change light came on this morning and i had 2500 miles on it. But i had already changed the oil on thursday night with about 2400 on it because i like to do the first one early to get good stuff in it. I am using 5w-20 synth blend for the first 10K then will change over to full synth. Going to go down on break today and try and reset the reminder.

is there a reason why your using 5w-30 when the owner manual call s for
5w-20 ?..calif..we have it in conventional, semi-syn and full syn..*pg. 549 of the owners manual..Lubricants which do not have both the engine oil certification mark and the correct SAE viscosity grade number SHOULD NOT
BE USED..ie, 5w-20

our local Speedy has it as well as the dealer..seems the dealer is now offering
oil changes $2 under Speedy s..and they re using the semi-syn oil..

Yes --> http://www.machinerylubrication.com/Read/518/motor-oils

specifically:
Temperature has a big effect on viscosity and film thickness. As a point of reference, one SAE grade increase in viscosity is necessary to overcome the influence of a 20°F increase in engine temperature. At a given reference point, there is approximately a 20°F. difference between viscosity grades SAE 30, 40 and 50. SAE 20 is somewhat closer to 30 than the other jumps, because SAE 30 must be 30°F higher than SAE 20 to be roughly the equivalent viscosity.

In other words, an SAE 20 at 190°F is about the same kinematic viscosity as an SAE 30 at 220°F, which is about the same viscosity as an SAE 40 at 240°F. This approximation works well in the 190°F to 260°F temperature range. One might be surprised at the slight amount of difference between straight viscosity vs. multiviscosity oils with the same back number (for example, SAE 30, SAE 5W-30, and SAE 10W-30).

If an SAE 50 oil at 260°F is as thin as an SAE 20 oil at 190°F, imagine how thin the oil film becomes when you are using an SAE 5W-20 and your engine overheats. When an engine overheats, the oil film becomes dangerously thin and can rupture.
Since Summer is coming, I wanted the slightly thicker oil to handle our 98 deg. F days here (I do run 5w20 in the winter). Also, this is probably why Jeep only gives the 'Riot a 1000lb tow capacity without the oil cooler, and 2000lb with. From an engineering standpoint, I'd also argue this is the reason our jeeps have two coolant thermostats, a main stat which opens at 180 deg. F and a secondary that adds additional cooling circulation at 203 deg. F. Hotter temperatures produce better fuel economy and less emissions (my wifes GMC runs at 220 deg. F), yet this modern engine runs at a relatively cool 180-190 deg. F? And to conclude, Chrysler has released a letter (which is archived somewhere on this site) saying 5w-30 is also acceptable and will not void the warranty. YMMV! ;)

I suggest you read those carefully, and pay attention to the wording. Chrysler is not "recommending" 5w30, or "un-recommending" 5w20; just saying that if 5420 is unavailable, 5w30 which meets certain specs is okay to use. The TSB referenced specifically references export vehicles because in some places 5w20 is not yet common.
Neither vis is going to kill you engine, but 5w30 has not proven itself in any way more beneficial than 5w20. I haven't seen any bad UOA's with any 5w20 oil in any brand.
Of course, do what makes you feel good.

Whether it's a domestic or international model doesn't mean anything where the engine is concerned. It's the same engine. 5w20 may not be common, but the wording is pretty specific.
The Manufacturer recommends using SAE 5W-30 engine oil for all future engine oil change maintenance intervals.
I personally feel 5W-20 was purely a CAFE standards move. The fact that you need an oil cooler for the 2000lb tow capacity, and our Jeeps run at a relatively cool 180-190 deg. F also suggests they are protecting the lighter weight oil from shearing. These are just my observations and speculations from the information available and YMMV.
 
#26 ·
It says specifically for export models, and it's for the reason I gave. I haven't seen a single example of a decent 5W20 shearing, although many 5w30's will shear considerably. The TSB also states that any 5w30 used must meet the listed specs I would like to see any documented case of an engine worn out or damaged by using 5w20 oil.
Like I said though, people get religious about this, and if running 5w30 makes you feel better, it's not going to damage anything.
 
#27 ·
I only use 5w30 in the summer, then I swap back to 5w20, but full synthetic in both. I suppose as long as people don't go super cheap on the oil, it should be just fine under normal driving conditions and proper changes....

Hmmm, I'm from the UK, and our service intervals are 9k miles,
I bought ours as an ex-demo from a main dealer and it wasnt serviced until 10k, so I have continued the interval. (10,20,30 etc)

I know we aren't as warm or dusty as you lot, but 3k miles between oil changes !?!, the dealer charges ÂŁ60 ($100) for the oil alone, I can get it locally for ÂŁ40.

My wife's Seat ibiza has a 20k service interval, it has a VW 2.0 litre Turbodiesel engine. Sound familiar ?

"Thicker in summer, thinner in winter" is what I've always done. 10-30 oil can be a problem when it gets -0F. Jeep recommends the engine heater if it gets garaged below -20. At -25 Ignatz still starts, but he grumbles. (Usually he's inside, but that time my old Pontiac's battery was weak and I knew darn well it wouldn't start in the AM if I left outside.)

I don't have much experience at high temps, but it can hit 90+ in summer, even in New England. If I were much south of here I'd talk to an oil-change place for the low-down; they'd know what's going on in their area/climate. The dealer is just going to read the manual to you.

motor oil

Motor oil is a never ending discussion amount motorist.

Here what i know about motor oil.

Conventional multi-grade motor oil start with a oil base. Some additive is add to the oil to increase viscosity at low temperature.

The first number is the winter viscosity. 5W is more fluid than 10W at the same cold temperature. The second number is the normal operation viscosity at the working temperature.

Your engine was design with a specific working temperature (control by the thermostat) and a specific viscosity in mind. In this case SAE20.

Back in the days. User manual request to change motor oil according to the kind of temperature the car was use in. Ex for my old car: 5W30 bellow 0C (32F) and 10W30 over 0C (32F). They both have the same viscosity at working temperature but 5W30 has a lower temperature of operation and more additive. They did not recommend keeping the 5W30 year round. I don't know why.
This lead to confusion to customer, so now 1 oil fit all.

If your car never go in winter condition you may not need the 5W. but it's important to stick to the 20. Some old car owner used to change to higher oil viscosity to reduce oil consumption

I don't understand what is the gain to change from 5W20 in winter to 5W30 in summer? Maybe lower fuel economy with 5W30 as the viscosity will be higher for the same engine temperature!! ;)

BTW. I prefer synthetic oil.

I have a 2010 Patriot 2.4L with the manual, currently I have 30,000kms and am just changing my oil as the indicator just came on again. Now the question I have is after the break in I switched to 5w20 Mobil1 synthetic oil and drive 99.5% highway (mountain passes), my weekly trip consists of 1000km drives each way only stopping to fill up with gas but even before 5000kms the oil starts to get dark (not black) and I'm changing it here at 9000kms and its dark but again not black, but there is a bit of smell of gas in the oil. I was just wondering if this is normal or not?

Any ideas? I plan on keeping this patriot to 300,000kms plus so I want to make it last :)
 
#34 ·
Hmmm ..sniffing oil....thats a new one on me .....& Ive been driving 48 yrs...lol

Have a dealer check it or get an oil analysis through Blackstone or some other company that offers that service. Gas in the oil is not a good thing.
