Oil gauge

[RoadKing]

Hey, do you guys trust the oil gauge on your bighorn were tells you what percentage of the oil life is left?

I bought a used 22 Big Horn and I’ve got about 4000 miles on it and the gauge says it still has 46% of oil life but I don’t know what oils in there or what filter so I feel like I should probably change it

That oil life is an algorithm based on driving. If You wanted to know status of Oil, would need a UOA. If you just bought the truck, smarter to change oil and filter anyway. Probably original oil from factory and needs to be changed. There are 2 good threads ref oil and filters. I use a full synthetic oil filter and use full synthetic PUP 5 W 20 oil. I read somewhere they may have switched the recommended oil on the 22's. Look at yer manual, oil cap and get it changed. All IMHO.....

If it's the factory fill, it's probably Pennzoil 0W-20 (or 5W-20) with a Mopar filter. The percentage is probably right based on what the driving was like for those 4000 miles. This would be a good time to get it changed and get those new-engine wear metals out of the pan. To answer your question, I don't pay attention to my OLM percentage...I just change it every 5k miles because it's easy to remember.
