Some Low Ash Oil info from Shell

Posted by Janicholson on April 15, 2013 at 12:40:35 from (199.17.6.78):

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.

Their reply follows:

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
