the 2012 3.6 recomends 5w30 so i dont think it will be an issue

 

Nice, I'm coming from a built 08 Sti. Looking forward to normal oil changes and brands. No more amsoil full saps...... Although it was great oil. Just costs a bit when u change at 2000-3k depending on track n dyno time. Gl w the jeep bud. N enjoy

 

I like Royal Purple filters and 10w 30 oil.

 

I have a 2013 JKUR Manual Trans with a Magnuson Supercharger. Please just take this as my 0.02 cents, not trying to start an argument on this topic.

I have been running Mobil 1 Extended Performance 5w30 (rather than the specified 5w20). Just started running a K&P (not "K&N") 2-piece stainless steel permanent oil filter because it's the only filter that can fit with my Magnuson Supercharger. It is damn near impossible to use an OEM size filter with the Supercharger due to its air intake configuration. I was wary of this permanent filter, but after doing some extensive research, I feel fine using it. I do an every 10,000 miles Oil Change Interval (OCI), though I have done 15,000 in the past without issue. I have not done any Used Oil Analysis (UOA), though I have used Mobil 1 Extended Performance and Turbo Diesel Truck full synthetic with very good long-term results on other vehicles using 15,000 mile OCIs. I am a fan of full synthetic mainly because when you figure the cost of doing 2 or 3 every 5,000 mile Dino OCIs vs. a single OCI every 10,000 or 15,000 OCI, it is lower cost (one oil filter vs. 2 or 3) and less of my time. BMW, Audi, Porsche and others routinely do an every 10,000 mile OCI on full synthetic as part of their scheduled maintenance. Pretty much all fleet vehicles, including Ashland Chemical (makers of Valvoline) use an every 5,000 mile OCI. I ping on these points only because many people still profess as to how critical and every 3,000 mile OCI is; I would argue that this an uninformed or hyper-vigilant perspective.

 

Iuse wix filters and quaker state 5/30 regular oil ever 3000 idk i got ver 93,000 miles on mine now still runs like the day i got it ! Not changing my method i did use one qt of pen this last time because they ran out of quaker state 5/30

 

3000 miles is a bit too often but clean oil is the best oil. You can go twice what you are doing and simply change the filter (and top up the filter oil loss) at 3000 then again when you change the oil. I run my Synthetic for 16,000kms which is 10,000 miles.

 

I bought my 2012 new and drive it for 8 yrs and 108,000 miles. Synthetic oil every 5000 miles because that is an easy interval to remember. I know I could have gone up to 8000 mile intervals, but again, 5K is easy to remember. I used different brands of oil and filters. In my opinion the brand does not really matter. I tracked MPG for every single fill up over 108,000 miles and could never detect an MPG change and could never detect a particular brand being better or worse. I did not use Mobil 1 because it does not carry the Chrysler certification and I had a lifetime warranty.

 

I use full synthetic oils and those with high mileage additives to reduce carbon sludge build-up in the engine. Pennzoil Platinum High Mileage 5W-30 Full Synthetic Motor Oil, 5 qt - Walmart.com - Walmart.com is one I use if I don't use Mobil1. Valvoline Premium Blue RESTORE is one that the Bob is the oil guy blog swears by. One of the Cummins diesel engines developed a bad history of sludged piston rings so Valvoline and Cummins collaborated to formulate a cleaning oil as an alternative to replacing the piston rings. It is expensive but the oil is very good and cleans over the whole oil change interval like Auto-Rx does. It is now marketed to work in both gas and diesel engines.

The CAFE (Corporate Avg Fuel Economy) rules have made mfrs use lighter oils to reduce resistance in the engine to improve gas mileage. I do not adhere to the CAFE based oil viscosities unless the engine has a turbo that has a history of oil starvation. My 2019 Honda Accord Sport has a turbo and it is still on warranty so I use their recommendations. I use the 5w 20 in winter and 10w 30 in summer for my jeep. I use mobil 1 filters or their extended performance filters if I am using BG EPR or Auto-Rx to clean an engine. I adjust OCI by how much highway mileage is on the oil.

 

Valvoline Blue Restore is a great product, but as far as I can find its a DIESEL engine oil and much higher viscosity than our V-6 gassers spec. There are few oils that are rated for use in Gasoline AND diesel engines and as such it is not usually a good idea to use a diesel oil in a gas engine and vice-versa. Its easy to tell by the API rating code will start with an "S" for spark engines and a "C" for Compression ignition engines.

I have been so far very pleased with Rotella's Gas Truck Synthetic oil, which does meet Chrylser MS-6395 requirements.
