Title: Definitely NOT recommended by me!!!
Review: Have used multitudes of different brands, grades and weights of oils and oil additives on both personal and fleet vehicles that I used to be responsible for maintaining. Many of these lubrication based products were analyzed at a lab after use to determine their lifespan and effectiveness. Having said that, I would NOT recommend this product based on my personal experience. Engine operating temps went WAY up, oil thinned out and broke down MUCH faster than normal, etc... Having worked with other lubricant additive products, my experience with Dura Lube was highly negative to say the least.Would suggest checking into Tufoil if you want the real deal in terms of oil / grease additives. It not only works as claimed, but has NASA approval and is ranked by the Guinness Book as being the slipperiest i.e. "best lubricating" substance known to man!!! Hard to beat!!!
