I've got three Jeeps with the non-roller, sliding-tappet 4.0 engine. Excluding all the diesel oils that get a high rating, what is the most important ingredient in oil to keep these engines healthy?
Okay, the reason I ask this question is that there is young adult in the area who just bought a local service station. Included in his purchase was everything that was in the property, in other words, if an item was inside the property he purchased, he gets to keep it. After doing inventory, he found hundreds of quarts of Universal (brand name) Eco Ultra engine oil in 5W-20, 5W30, and 10W30 weights. It seems the previous owners had purchased this oil thinking it would be the next big fad and all of the local customers were afraid of it. It was then shelved. (Side note: This is reclaimed oil that is rerefined and new additives are added. We all know what happened to a certain name-brand of oil that tried to sell their variety of reclaimed oil.....)
Anyway, this is the website for this oil: http://www.ecoultraoil.com/
The new owner is selling all of it for $2/quart. Half of me wants to purchase it to help the kid out. The other half is hoping it would be a good oil for my Jeep flat tappets. It is also an SM rated oil, which doesn't scare me one bit. Matter-of-fact, I feel that this oil would be ideal for my Jeeps, more so than an SN oil. So I've bought some 10W30 oil, I'm waiting for an oil analysis kit, and if the ingredients of this oil are right, I might buy quite a few of the 10W30 quarts.
So exactly what ingredient(s), and at what concentrations would be ideal that my Jeeps would love the stuff? ZDDP?
Maybe just the veterans on this site know what the stuff is, but I've also got some S.L.O.B. in the garage that I could start using.
