I wouldn't want an oil that causes a vehicle to quit on it.

I'm liking the RGT a lot, use less oil when it's in my engine for some reason. I've been using it for the past year. Prior to that I was using Pennzoil Platinum. Honestly if I had to chose between the two I'd pick the RTG. And you can't beat their rebates.

I used Valvoline Daily Advance 5w20 in my Caravan since new. I did try Havoline 5w20 and between fuel mileage and thinning out I will stay with Valvoline. I am doing 5k but might just push it to once a year since I average 7500 miles a year as per manual. I am thinking about going to Valvoline Advanced since it has held up well in sisters Altima in 0w20. I didn't reset OLM last oil change but will be monitoring to see when it comes on then make decision on oil but will be Valvoline. 18 Grand Caravan SE 14k 3.6

Does anyone use these for their Subaru's? Debating between the M1 extended performance 0w-20 vs the advanced fuel economy 0w-20. It would be for a 2016 Subaru Impreza 2.0 non turbo

If you are following the manual for oil change interval the AFE is more than adequate.

My wife had a 2014 Jeep Cherokee with the V6 Pentastar. I used any 5W-20 synthetic / high mileage synthetic that was on sale. No problems, except that one time that the stupid [censored] plastic oil filter housing cracked...

Just replaced ours last weekend at 81,000 miles. Also had to do the oil control solenoid on the oil pump last winter (that was a bear.) Such a PITA these things sometimes.

It never had, even overseas, a weight specification greater than 20. The previous generations of t The fact my JL Rubicon, even with 35" tires, can get 21.5 mpg is significant evidence this engine is different. When traveling with two 2 door JK's with Pentastars, which were lighter and had the same size tires and final drive gearing, we saw nearly a 4mpg difference in gas mileage over 2000+ miles of driving the same trip together. Folks, that's not the 20 weight oil, that's a redesigned engine. (Ok, the aero is supposed to be better with the JL, but it isn't 4mpg better.) I hope that helps clear up some of the confusion between these two generations of the Pentastar.
FTR I'm sure you already know this. I'm not sure if you're talking 6 speed stick, which the JK and JL have. The JL 6 speed is not the same as the JK 6 speed, it is supposed to be an improvement. With regard to the automatic, the JK uses the NAG1 5 speed, the JL the ZF 8 speed. I'm pretty sure that would account for most of that 4 mpg difference.
Yep, I have both, a JK Rubicon 6 speed and a JL Rubicon 6 speed. The JL's Aisin transmission is indeed vastly superior to the JK's NSG370. However, I think several factors are at play for that mpg increase, including aero, probably the transmission, and the engine. I've driven enough Pentastars to know that the PUG is stronger and revs just a little more freely, IMO. Not by alot, but it's there. Read up on the PUG. They did a great deal of friction reducing in the engine. There is significantly reworked with both power and fuel economy in mind. I've heard people talking as if 5w20 is a thicker oil than 0w20. Take a look at kinematic viscosity and you'll see that Mobil 1 EP and AP are thicker at 100 degrees C than many 5w20 oils. I believe they are 8.7 and 8.8, respectively. They also have higher flash points and lower pour points. I believe them to be superior oils to the 5w20's, and have more PAO content. Back to the conversation...another 0w20 that I think is good is Pennzoil Gold. It is advertized as a blend but the specs look really good. I'm betting it was the factory fill on my Jeep.
