Just a warning that oil for modern gas engines may not contain enough zinc additive for old flat tappit engines, Diesel oil or especially straight grade oil 30 or 40 cf-2 for detroit 2 strokes should be better.

yep this has ben a problem for some time now, gets to be hard on cam shafts (learnd the hard way) every engine we biuld here gets run in on this
http://www.joegibbsracingoil.com/produc ... index.html then they all get switched over to royal purple 10w/30 for the gas engines and the deisels get switched to amsoil 15w-40

Is any of the Lucas stuff any good?
Been thinking of using RotellaT 15w40 too, I only run my stuff when its warmer

Thats all I use in ALL my engines. But then again my old girls don't work either It'll be interesting what they have to say about it.

I was thinking Rotella 20w50, my Farmall Super C is new to me, but I have it doing light chores around my property, and intend to plow a garden spot with it later this year. The operators manual says 20 weight low detergent.

In my opinion the safest easiest oil for warm weather and old engines is straight 30 CF-2 oil designed for the old detroit strokes, because they haven't been manufactured for years the formulation shouldn't change, some of the new diesel oils CJ and later may have lower zinc content.

lucas is great for gear box's but im not so shure about engines. from personal experience i notced that in engines with hydralic lifters the oil with lucas doesnt get to the top of the motor quik enuff, therefore causing rocker arm chatter at high rpms. solid lifter engines havent noticed any difference other then hard to crank over when its freezing out
