What ever my dealer puts in. Its 5w20.

 

PP or Mobil 1 5W-30 is the best.

Hello,

Currently using Pennzoil Platinum 5W-30.
Best spec. for wear and fuel economy.
It meets Honda HTO-06, very solid.

 

Motorcraft 5W20 semi synthetic is $12.50 for 5 quarts at my local Walmart. Napa Gold filter $5. Changes every 4500 miles.

 

Was running dino on the first two (original and 1st change), on the second, switched to Mobil 1 5w20, at 8000, my last change, went to Mobil 1 5w30 and she seems to run better and get better fuel economy. And yes this is Wisconsin so the defrost has still been on for most of the drives and I still drive it like I stole it.

 

5w20 is nessary for the vvt to work proper

 

I'm not sure I follow you? Can you elaborate?

 

Mobile 1 5-30 here. It does seem to get better gas mileage with the Synth.

 

I use mobile 1 Synthetic 5w20 in both my 2007 Jeep Patriot and my 2008 Dodge Grand Caravan.

 

FWIW, my Patriot is leased, under warranty and all oil changes provided free by the Jeep dealer for 4 years. This means I have NO idea what grade of oil the Jeep boys are putting into the Pat.

 

Probably and orphan's tears.

 

Over here in the UK its suggested 5w30 on the CRD

So use Castrol Edge 5w30 which meats VWs Longlife Variable Servicing.

Use the same stuff in our Audi A3 TDi ...

Change the Patriot's every 9k
The A3 does 2yrs 20,000 miles on the same stuff ...

Was tempted to trial a similar oil change interval to the A3 ... but just do it every 9k

Gives me a chance to get the tyres rotated and check everything else ...

 

you can read all about it in the owners manual.

all the vvt is the cam advancing and retarding to time your valve, the thinner the oil, the better it works,

 

Nothing in my owner's manual says anything remotely like that.
Just says 5W20 is recommended. No mention of VVT or any other reason.

 

I use mobil 1 5W-20 Works amazing

 

Mobil 1 5w-20 synthetic.

 

I use the Motorcraft 5w-20 synth blend.

 

5W-20 what the book calls for-the dealer I take it to uses Pennzoil, will be switching to Royal Purple next oil change.

5W20 vrs 5W30

Hi. Said it before in another thread, and I'll say it again: The manual for USA 'Riots says 5w20; the oil filler cap says 5w20, why run a heavier oil? How does that make sense for better lubrication, quicker lubrication on start-up, and better flow rate through the oil ports and returns? Higher MPG with 5w30 is just confounding, because driving conditions, style, load, time of year, everything, would have to be exactly the same to test that theory. I can maybe understand a heavier oil if your 'Riot is running around in the desert SW in July, or 0W10 for the Yukon in January, but I haven't seen any info on that. Maybe the most important questions are: Oil change interval; oil filter quality; dino, blend, or synthetic oil. [PS I know the 'Riots made for Europe require 5W30, but don't know what the reason is... maybe 'cus they are diesel.] The beat goes on. PS. I use Castrol Syntec 5w20.

 

Not correct.....

You will not get quicker lubrication on start-up with 5W-20. Both 5W-20 and 5W30 are 5W when cold.

You are correct about the manual and oil cap, however the reason for that is the issue. Chrysler agreed to 'recommend' 5W-20 so they could use the very slight improvement in fuel economy to hit the US Government CAFE targets. All things being equal 5W-30 will protect the motor slightly better and provide better fuel economy in the long run. (Especially if you opt for a synthetic)

Do a search here, on Google and visit 'Bob is the Oil Guy' for more information.

Mobil 1 5-20 synthetic

 

In hot weather and dusty atmosphere like in Greece only the 5-30 synthetic will stand the demands.

 

Here is some damning reasons to not use 5W-20. These have been well circulated on the forum:

Jeep Patriot 5w-30 TSB

Mobil 1 Jeep Patriot Recommendation (5w-30)

Letter from Chrysler advising 5w-30 can be used

EPA Letter regarding 5w-20 (explains what car makers need to do so 5w-20 can be used to help them hit their EPA CAFE targets)

 

As far as the Mobil 1 recommendation, when I use the Mobil 1 website, it recommends 5w20, as does the Castrol website.

 

I did misspeak.
I wonder how Chrysler will handle the lifetime warranty if 5w30 is used?

 

The links in a previous post show you would not have any warranty problems.

 

I use 5-30 synthetic in my "Riot" and I use 20-50 in my motorcycle...
I hit the rev limiter once in a great while in the Riot, (I thinks it's set around 6300 RPM...) But, the bike sees the rev limiter almost once every trip! (It's set at the factory at 5200 RPM.) The bike is a 1.7 liter "V" twin and as y'all know the Riot is an in line 4...
Both machines are used in south Florida (USA) and I'm lucky to see temperatures in the mid seventies once in a while... Typically like last nights ride home... It was 85 degrees and I was traveling 85 MPH for nearly an hour...
Under those conditions, my Riot needs all the protection it can get...!:Racing:

 

I used Mobile 1 5w20 for the first time this winter, I had been using M1 5w30. I wasn't going to be towing anything, so I figured I'd try it to compare.
Didn't really notice any difference driving, but when I changed it at 5000km, it came out very black. The 5w30 never looked that black after 5000km.

 

i put 10w30 Acdelco synthetic oil.... happy with it no problems so far, it has 3,000 km´s running with it.

 

I use regular 5w20 in the Winter and 5w30 in the Summer. I highly recommend a good quality filter and check oil for discoloration (contamination) at 3000 mi.
