Only one engine in the family uses syn oil and thats my sons Madza,Every thing else from the 76 k5 to my wifes 2010 car and all my other engines get regular motor oil except the race car which uses a high zinc content oil.

Syn oil is supposed to be good stuff but my engines seem happy  with regular oil.

Bill...    What oil has a high content of Zinc...??

Was using Brad Penn -Penn grade 1 partial synthetic 20w50 hi performance oil,$6 quart,Had good luck with it. Switched over to Kendall GT-1 high performance racing formula,and have been having good luck with that.

Two reasons I switched-first and formost was the price--zero $ per quart,sponser pays for it and second lots of the sprint car teams are using it and I figure if it good enought for a 900hp ground pounder its good enought for my 450 hp super modified.

If I'm turning 7500 rpm in a loose tolerance race engine, I'd want 20/50 or straight 50 racing oil, or something as well. 6500 is about the most any of my engines see, and most wouldn't turn past 6000 if hooked a turbine to the front of the crankshaft.

No one brought up the case of oil leakage...  If your'e tractor leaks a little,,   The synthetics are much thinner... like 0--20,,,,10--30,, and so on..   I run  20--50  Royal purple in my  400 HP classic...  I have no problems thou...My tractors get strait 30 wt dino oil...

synthetics are not thinner they have smaller molecular size which allows more molecules in the same space so allowing more lubrication potential in a tighter tolerance, that also means they can fit through a smaller gap in a gasket or seal , I use mobile 1 10/30 full synthetic in my H16 to allow for better lubrication with the old style oil plunger pump for the valve train lubrication, it seeps a little more than conventional oil but i don't mind as it keeps the engine from getting rusty between uses as i don't use it as much as i used to, the oil has been in the engine for 2 years with no noticable change in look or feel and doesn't seem to draw moisture either during storage so i'm sticking with it for that engine but my 67 750 gets old style oil as it has no pump . I put dexos2 in my TRA-10D to clean it out and it got most of the condensation and crap out of the engine but i am not sure what i am going to use next
