Synthetic oil

[Boogieman]

I have read non synthetic oil is better for the 3.6 engine to guard against dry starts. Just purchased a 2015 JK with 70,000 miles and need to do an oil change. Appreciate advise on the subject. Currently engine runs great, no ticks, just smooth quiet idle. Hope to keep it that way.

I'm not really sure it's better for cold starts, but they do say you can get better mileage from using it. I like to add a little Lucas Oil Additive to my oil so that it makes it kinda sticky.

He is referring to a member of the TJ forum. TheBoogieman a very nefarious member at that

Whew, glad he is not the one with the red TJ.

The TJ forum was a blast. I miss my TJ.

I still have mine, after tomorrow it will be on Jack stands in the shop getting a spring transplant.

Taking out the old RC's and installing the new Rockjock's

Taking the TJ to Coalmont OHV tomorrow for the last ride on the RC's.

Safe to say no one has input on the oil question?

Back in 1990, I spec'd out a Peterbilt truck for the company I was working for. Something I will never forget, was on the diffs, Peterbilt would offer literally DOUBLE the mile warranty if we took delivery with synthetic fluid in the diffs. another story was a earthmover co that I work with did Caterpillar's local dealer network for "SOS", or scheduled oil samples in all their equipment, diffs, planetaries, engines, trans, etc. They found from the SOS comparison that Synthetic fluid (especially engines) would gain 20-30% life in hours. So a $40k engine would go 12500hrs instead of 10000hrs, etc.. I always use synthetic in my entire fleet. I have for 20+ years. Forklifts, flatbeds delivery trucks, personal vehicles, etc.. The only vehicle I do not run any synthetic in is my son's Tesla. I even use synthetic grease when possible.

Just a personal testimony here.
