I am in sales (office equip.) and one of my long term customers is a good size construction company. Last week I was talking with there GM and being an oil nut like so many of you here making small talk I asked what oil do you run in your fleet of construction trucks, dump truck, dozers, loaders, and the many pick up trucks you use? He replied its funny you should ask as we just finished a rather long intense study of oil and engine wear based off of some 50+ Different types of vehicles running a variety of different oils at different lengths. This study took us several years and cost us quite a bit of money in UOA tests and what we found was it did not matter what you ran for oil as long as it met the manufacture specifications. Running Dino oil or synthetic did not seem to show much difference what did seem to make a difference in wear numbers that was clear was we had 12 vehicles of different types that we just used one brand of oil the entire test meaning we would pick an oil for an engine and stick with it for that engine for the test length. What we found was the engines that showed the most or largest wear numbers were the ones we would switch from brand to brand of oil. The lowest wear seemed to be from the engines that stuck with one brand of oil for the life of the vehicle running either Dino or synthetic oil sticking with one brand no matter what brand of oil it was. Anyway the end result we picked an oil distributor that had oil that met all our needs for gas and diesel that met our engine specifications and we get the best price and just buy in bulk and stick with one brand. Right now that happens to be Mobil oil all in conventional.
I thought this was interesting and I just thought I would share.
