[QUOTE="swampratt, post: 3927832, member: 15054"] I looked at oil specs and the additive packages and really looked at the Zinc and Phosphorous levels. The old Havoline from the 70's Zinc was in the 1200 ppm range on one article I read. It was my favorite for a long time and was my Uncles favorite. He raced NASCAR for many years and began when it was on dirt tracks. He told me of all the engines he tore apart in his shop the ones that used Havoline were the cleanest. Additive packages can make or break an oil as we know. My dad told me the "oil" does not break down it is the additives that give up and the contaminants in the oil that kill it. I do not know how true that is. But in my mind I always thought conventional vs synthetic it does not make any difference as the same contaminants are there and the stuff needs changed at the same time. A lot of oils do not have good cling and when you let an engine sit for long periods the parts become "dry" and that is a killer. I have done some lubricant tests and had Mobil synthetic oil in the test. My test was more of a rust inhibitor test though. Flat piece of mild steel I sanded smooth and shiny. 24" long 2" wide 3/16 thick I sectioned off 2" spaces with masking tape and applied a different lube in each section and set it out in the weather to rust away. Mobil 1 synthetic 5-30 was the first to turn to rust and it did not take long to do it. Mobil synthetic transmission fluid was also used and it rusted just as quickly. A mix of the 2 rusted quickly also. Now that information makes my brain think what happens on a cylinder wall inside of an engine that has sat for long periods???? Yea I have had some engines just sit and rust away and not rained on just the additives in the oil react with the humidity in the air and bad things start happening. Now the winner of the test i performed was Quick silver 2 stroke outboard engine oil. No rust. Joe Gibbs now Driven has an oil that was developed to combat this rust issue in a stored engine. Read about that oil here. [URL unfurl="true"]https://butlerperformance.com/i-24453781-driven-hr1-hot-rod-conventional-motor-oil-15w50-quart-jgd-02106.html[/URL] .. [/QUOTE]
