it seems harder to find the engine oils these days that meet at least the following:
40 wt
API CF-2 rating
Low % Ash (< 1.00 %)
Rotella T-1 (straight 40) seems widely available at a reasonable price, but it is at the upper limit of
1% Ash.
Some of the other engine oils with lower % Ash ratings have gotten pricey.
What are you all using?

Re: What engine oils are people using.
I just changed my oil in our 671's and used Chevron Dello 100 40WT, it was pricey I got six 5 gallon pails which will do two complete oil changes on the two engines. I gave $112.00 a pail and talked them into free shipping if I got all they had in stock at the time last December at Santies Wholesale Oil company www.santiemidwest.com

NAPA's 40wt house brand is made by Valvoline and is well within the DD specs. It is also relatively inexpensive. The last I bought was around $70 for a 5-gallon bucket. Check with your local NAPA store, if they don't have it in stock they can usually get it within a day or so.
