Best engine oil weight?

[csquared63]

I need to change the engine oil in my 790. I see the recommendations in the manual, with 5w-30 covering the biggest temp range, however I cannot find that weight anywhere.
I mostly use the tractor to plow snow so cold starts matter more--we sometimes have periods of -10F, but it does get over 85 degrees here too and I'd like the protection there if I need it.

Can I use 0w-40?

Thanks,

Carl

That's odd because 5w30 is fairly common here in southern PA. I try to stick with what is recommended in the manual. Could you order online? Pepboys, advanced auto, true value, Walmart even?

Well I was looking for the Torq-Gard brand. I should have mentioned that. If I can just use a high-quality other brand, then I guess I'm good!

Thanks

Yes, you can use 0W-40. The 0 number just indicates how well oil will flow in colder temperatures.

I buy Castrol 5w30 for VW TDIs at the local VW dealership.

Have looked online for M1 0w30 ESP (exhaust system protection, for diesel DPFs) and occasionally find it for about the same price. Next oil change to the 2025R I'll look ahead of time online for it. Would be even better. Have the Castrol in the Isuzu diesel generator driver as well.

Other options are Diesel Engine Oil: Shop Engine Oil for Diesel Engines - AMSOIL

Can be shipped just about anywhere.

Oh, didn't realize you were looking for a specific brand... Ha.

5w-30 is typically an S rated oil not suitable for diesels. 10w-30 would be a good conventional or synthetic blend viscosity. 5w-40 if you prefer full syn.

Not any more, many brands carry 5W-30 C rated (Compression ignition) for diesel engines. Amsoil has 3 different ones alone.

Whatever. Go to an average auto parts store, Sams Club, Costco or Walmart and see how many C rated 5w-30 oils you find. The OP isn't seeing it either.
