A lot of us use synthetic 5w30, most meed the same MS6395....lots of threads on the subject of you do a search.

 

I searched 0W-20. It returned, "Sorry - no matches. Please try some different terms."

(I just searched 5W-20 with the same results...)

 

Put oil after the grade...here are a couple that came up.

Thank you.

 

Most of the "5WXX oil" search threads discuss 5W-20 vs. 5W-30.

Not much discussion is provided about 0W-20 vs. 5W-20.

IMHO 0w gives you about 5 degrees less then a synthetic 5w, great if you live in Alaska and it's -45 celcius, not really needed in most of north america, and completely negated if you use the block heater.
The w20 vs w30 debate is because that's what affects the engine at operating temps, which is what it sees the most of during use.

 

I have been using 5w20 Mobil1 since the Jeep had 600 miles. I swear by the stuff.

 

It is not recommended to use a block heater unless the temperature is below -20*F.

From the OM...

"Extreme Cold Weather (Below –20°F or 29°C) To ensure reliable starting at these temperatures, use of an externally powered electric engine block heater (available from your authorized dealer) is recommended."

0W indicates a cold-start viscosity, at a lower temperature.

An oil that thickens less when cooled and reaches proper viscosity sooner will reduce wear on an engine and associated components.

 

If there is no wear at start up using 5w30, how much less then "no wear" will 0w20 get me?
As long as the oil is flowing, it's protecting the engine, I have zero concerns of cold weather starting using synthetic 5w30 without the block heater down to -20C, PP pour point is -35C. The manual states WHEN you should start using it at low temps, not that you SHOULDN'T use it at higher temps then -29C. It warms the block and the oil....what exactly is that going to harm?
And if you are that concerned about what the manual says, why are you discussing using something other then 5w20? That's the only oil viscosity they recomend in the US for the Patriot....

"SAE 5W-20 engine oil is recommended for all operating temperatures. This engine oil improves low temperature starting and vehicle fuel economy. Lubricants which do not have both the engine oil certification mark and the correct SAE viscosity grade number should not be used."

 

I could not find out if the engine block heater has a thermostat and if it does, what the the on/off settings are. I do not know if the engine block heater will energize at 75*F. I only know that it is not recommended to be used above -20*F.

My question is, "If improved low temperature starting and vehicle fuel economy are a plus, why not use a 0W-20 synthetic?"

 

A) It's not cold enough for me, even here in Canada where it hits -30C, to justify spending twice the price for oil that would give me an added low starting capability inprovement from -35C to -47C.....block heaters come standard on Canadian Patriots as well, so really no benefit to me.

B) Fuel Economy gains are negligeable or non-existent, with the standard advertised gains being 1%-2%.
Going by the Mobil 1 website:

Fuel Savings Worksheet
Cumulative Miles 50,000 100,000 150,000
Estimated Savings* $147 $294 $441

So for simplicity, lets use 150,000 miles as the life of the vehicle, or as long as I would own it. Say we change the oil every 5000 miles, which is a nice average number that most folks would probably follow. That's 30 oil changes for the life of the vehicle. Mobil 1 advanced FE oil would run me $20 more per change, or $600 more per the 150,000 miles.....so I would spend $600 extra on one petroleum product to save $441 on another one.

Do you sell 0w20 oil or something for a living?

 

Okay - 0W-XX oil does not prove to be cost effective.

Hmmm, maybe the cost will go down in the future. I think I will visit WalMart next weekend to compare the price of Pennzoil Platinum 5W-20 to Mobil 1 5W-20. I guess that Pennzoil Platinum 0W-20 is costly too?

No, I do not sell 0W-20 oil or anything for a living.

 

Either Pennzoil Platinum or Mobil 1 will do just fine. If you want to spend some more, go with Mobil 1 EP.

 

I use M1 5W20. I changed at 2500miles to this. I used Castrol Syntech on one occasion when M1 wasn't available. I didn't see any difference.

I have been a fan of M1 for a while. I use it for all my engines. You really see a diffenence when the oil is abused in something like a small generator or lawn riding mower. That being said, my research was done prior to the big M1/Castrol fight followed by M1 changing it's formulation. Who knows now?

 

Oil prices: Wally World on Second street, Reno, NV. 25MAR11

5 qt jug, M1 5W-20 $24.50
5 qt jug, M1 AFE 0W-30 $24.50
5 qt jug, PP 5W-20 $23.50

They did not have M1 0W-20 in the 5 qt jug. It was $6.37 a qt...

I did not see PP 0W-20

I may run M1 0W-30... One up, one down...

 

Mobil 0w-20 is made with higher quality base stocks than the 5w-XX oils. (GRP IV rather than III), oil has to be a higher grade base stock to meet 0w requirements. Also...extremely durable oil, meets GM 4718M (Corvette spec). 4718M is the spec that allowed GM to eliminate the engine oil cooler when they went from Tuned-Port engines to LT1 in 1992/1993. Very stout stuff. I towed a trailer for almost 3000 miles up and down three mountain ranger, did a used oil analysis after almost 4K on Mobil 0w-30 in my Ram....excellent UOA. 0w in the real deal.

 

Thank you for the feedback, mpco239.

So, if cost is the same, then running 0W-30 is not a bad selection???

 

I see a jug of Wally World 0W-30 M1 AFE in the future...

 

I have run Mobil#1 5w-20 synthetic since I bought mine and its the best bang for your buck as far as I'm concerned. A 5 litre jug at wall mart is about $35. There is just over 155,000km on my patriot and not one issue. I change my oil every 5000km and it always comes out reasonibly clear. I would however highly recomend an oil filter with an anti drain back valve. there hard to find for the pariot but the NAPA premium filter for the patriot has one.

 

I think most filters have an ADB, even though in the case of the Patriot(among other vehicles) the filter hangs vertically upside down, so ....

 

Thank you for the info about the NAPA oil filter. I just "reserved" one (FIL 7060 @ $6.39), on-line, at my local store. You saved me $6.00 over a M1 filter (M1-113).

 

FYI. Napa filters are re-branded WIX filters, and their "Platinum" and "Gold" filters are actually identical besides the labels.

 

Roger that.

 

I went w/ the 0W-30. I believe it will be fine for year round service - M1 AFE 0W-20 Viscosity @ 100ºC, 8.7 cSt, M1 AEF 0W-30 Viscosity @ 100ºC, cSt 10.9 cSt. A 20 weight oil can go up to 9.5 cSt @ 100ºC.

 

Like I said, most filters, at least the ones I've ever bought, have an ADBV. And their purpose is to keep oil in the filter.

 

Filters without Bypass Valves are pretty much exclusive to GM vehicles as they have them built into the engine, so they are not required in the filter.
If it cross references to the Patriot on the filter manufacturers website, you are good to go. Pretty sure all modern can filters have anti drain back valves.

 

Interesting subject. I used a Mopar filter on my first oil change, then I used WIX on my second oil change. The WIX filter has a very apparent anti-drain back valve, but the Mopar filter didn't even seem to have one. Unless Mopar put their valve at the back of the filter, I'm not sure it has one. Maybe it's in my head, but with the WIX filter in, cold start ups don't seem to be as rough

 

I used a SuperTech ST10060 filter the other day when I changed my oil. It was $2.87 and had an anti-drainback valve.

Incidentally the Wix part number for the Patriot is the same as the 6.0, 6.2 and 7.2 Corvettes.

You could tell everyone you use a "corvette" oil filter on your Jeep.

 

The PAT is just about at 12,000 miles, time to change the oil again.

 

I know this thread has been dead for a while but I know some of the guys are still on here from this thread. I'm about to change my oil I'm at around 10,000 miles. This is my third change. Last change was to a semi synthetic at valvoline. I'm now switching from 5w-20 to M1 0w-20. From all the research I've done and trying to see if anyone has had any issues with the 0w I haven't found any. People seem to like it because it's great at low temp start ups but also works great at normal driving temps the same as the 5w-20. Wanted to see if anyone else has been running 0w-20 and their experience with it. Not to mention the 0w-20 jug at Walmart was close to if not the same price as the m1 5w-20. Which was around 26 bucks in MA.

 

Appx 20K miles on 0W-30 M1 AFE.
