Wow! Look at all the above RE:'s Roger/Randy: The term Dino oil is short for Dinosoar crude oil formed millions of years past (Fossil Fuels) pumped out of Mother Earth.(possibly containing remains of everything that was living or growing at the time?)The Dino crude is then (cracked or refined into every thing from Kerosene to Unleaded Gasoline,Motor Oils,and hundreds of other great things.)Synthetic oils are almost all manmade,much more costly to make.(I think all Synthetics use a small amount of conventional/Dino as a oil additive carrier)I am by no means a oil expert,just a good listner/reader of the results I have seen.As for the Brands: At our Engine shop here,over the years we have been given the following Oils:(For no cost,to ship with and recomend for the racing teams)Valvoline,Mobil 1, Chevron-Exxon,Conoco,Pennsoil,Torco. All Brands in Conventional and Synthetic Blend (25-40 percent Synthetic oil,as they do mix well),also in 100 percent synthetic.This post is not going to be advertisment,But, I will say all the above worked very well.We send engines out during summer months with 15w-50/15w-40 grades with great results. The Chevron was a little different with 5w-50,but also saw great results,The owners soon thought they could find a little more power with running a lighter oil,ie:0w-40,5w-30,5w20,But the engines looked much worse after teardowns,The items in a engine that run hot ie: valve guides,piston pins,clyinder walls looked real bad after running the super light weight oils. This had to hurt power in the long run. Before this post gets any longer, I have a fleet of over 20 engines @ home/shop from 4 horsepower to over 500,including a TO-35 tractor,all use synthetics,15w-40/15w-50 summers,5w-50winters.I have had no problems in any.Most of the older units were flushed/cleaned out with sooner(more often) then regular Dino oil changes.(no solvents,additives)I would also agree with most of the readers of this post that using the costly syns. is overkill in most of my apps. But even if I had to buy it, I still probably would use it.hope this helps? Gregg/Ohio
