Wife has 2015 Jeep Grand Cherokee with 3.6L V6. About 140K on the odometer. Vehicle has had nothing but Oilzum 5W-20 conventional oil and Wix filters. Service performed as soon as vehicle tells wife oil change is due. Just bought similar vehicle for my use. Garage who serviced my new used GC said to use synthetic oil when servicing. Am I courting trouble if I use synthetic in wife's GC?
switch to synthetic

I mean at 140K why change it up now if it is working? I can see if you just want to have one type of oil laying around, but I don't think I would bother.
It's totaled.
First I've heard of it. Sounds like something from the 1930's.
^^I Googled it. Oilzum was made by White & Bagley in Massachusetts. The company was formed in 1888. One blurb I read said they made/sold oil in 1905-6 with a racing oil, Crystal Oilzum, debuting in 1912.
I love that they sell both Summer and Winter bar & chain oils.

right pabloYou joined thirteen years ago to finally post this question today? And your post concerns whether you should still be using some essentially unheard of regional blend in a modern car, or move to a synthetic. You should move to a synthetic, specifically Quaker State 0W20 full synthetic. You can certainly keep your BITOG name regardless.
I've changed vehicles with over 200,00 miles to synthetic. No problems.
I used Mobil1, the original 5w-20 version, in my 1958 Ford Wagon, 1971 Ford Pinto and 1970 MGB-GT (later 5w-30 version) . No problems.
Thanks for the reply. I might switch after the next LOF to use up the rest of the case.
