For some definition on Low ash oil, I asked Shell Oil Co. to discuss the ash level in current oil
My question was:
>I participate in a forum at Yesterdays Tractors. IH “Farmall” has
specified
>Low ash oil for use in its gasoline engines from the early 1960s.
We are in a
>discussion as to whether the current Low ash diesel grade oils are
of the same
>intended (or unintended) ash levels. My family has been a
consistent user of
>Rotella Oils, and would like to be assured that if we used 15- 40
Rotella
>diesel oil in a 706 Farmall gasoline tractor, that it would meet the
same low
>ash intentions as the IH branded oil from the dealer.

Dear Sir,
The information we have for the Farmall 706 (gasoline) indicates it called for an API SF low ash oil (max 0.5% ) for viscosity ranges of 10w, 30w, and 5w-30. No information on higher viscosity ranges is listed in our reference. Rotella T 15w-40 meets API SM specifications for gasoline engines, which covers API SF, but has a maximum ash content of 1%.
Best Regards,
Shell Technical
