The Tuul Crib 7,338 #1 Posted June 16, 2019 I’m looking at some engine oil’s online as well as local. I do know that 30 weight is what I will be using. There are some of you that use shell Rotella in their engines. All of 30 weight shell Rotella that I see says diesel engines. Does this matter? Share this post Link to post Share on other sites
953 nut 57,932 #2 Posted June 16, 2019 That is what I use. Tractor Supply seems to have the best price. 2 Share this post Link to post Share on other sites
The Tuul Crib 7,338 #3 Posted June 16, 2019 Thats what lm lookin at . What about the blend for Diesel engines. Does this matter? Will it harm these small engines? Share this post Link to post Share on other sites
pfrederi 18,334 #4 Posted June 16, 2019 (edited) Diesels can have ZDDP (or what ever it is) Rotella is all I use in my hard workers Edited June 16, 2019 by pfrederi 1 Share this post Link to post Share on other sites
pfrederi 18,334 #5 Posted June 16, 2019 Lots of old gas farm tractor owners use it also. ZDDP is good for flat tappets. 1 1 Share this post Link to post Share on other sites

lynnmor 7,566 #7 Posted June 16, 2019 I bought a new zero turn with a Kohler engine. I looked at the Kohler oil and saw that it didn't have the dreaded SN designation, so I bought a case. SN is the oil to keep the government happy because it is low in ZDDP which supposedly is harmful to catalytic converters. Share this post Link to post Share on other sites

ZXT 2,401 #9 Posted June 17, 2019 It is perfectly OK to run diesel oil in gas engines, especially older ones. There are no downsides that I know of. As was said, ZDDP is great for the cam and lifters and most brands of diesel oil still contain a fair amount. Share this post Link to post Share on other sites

The large lettering on the bottle will say diesel but read the fine print. It will have the diesel classification listed as CC, CD or CE something like that. The C is for compression = diesel If it also has SF, SG or SH it is the gasoline engine spec. The S is for spark = gas engine and you are good to go.

nylyon-(Admin) 7,484 #11 Posted June 17, 2019 I use Rotella for everything, the diesels get T6, as do the Audi’s. 30w Rotella for the small engines 2 Share this post Link to post Share on other sites
