John Deere Mower Fanatic
I'm new to this forum and Just wanted to get your thoughts on quaker State Ultimate Durability.
Did you know the oils you listed as "synthetic" are not real 100% synthetics?I don't know CJ, but I've studied and researched a whole heap about motor oils, and I think any good modern oil will pass the test for durability. Having said that, I use either Mobile 1, Valvoline Full Synthetic, and will probably go with that new Pennzoil super duper whatchamacallit synthetic made from ----- gas. Right gais I tell ye. Natural gas, not gasoline. No matter, I just believe in full synthetic oil, even in me old lawn mowers, two cycle engines, everything that has an engine.
