I work on old vintage motorcycles, most of which have a fair amount of oil and grease on the engine and transmission parts. These gloves are so much better than the run of the mill cheapo's that can be bought about the same price. Yes, these will tear like any nitrile glove, but these are very, very durable and do a very nice job of standing up to gas, oils, and brake cleaner. I've yet to find any better than these for the price. No complaints whatsoever.
I took the chance of ordering expired Loctite 330. It was jelled up pretty good and generally unusable. It was my fault for trying it and never called the company to complain as I took the chance and that is on me. Order the good stuff.
Had used aviation Camguard for years. Added as well to each quart of oil added to my Lyc 540 SIA5 aerostar engines. Went past TBO with excellent compressions. Oil analysis always normal.
Also add to automobiles but too early to see a benefit.
