Proper oil

[Wolfgang]

To all you experts on old tractors..
What is a good year round oil for Allis CA that is used very little.
Engine and oil pan cleaned of sludge....had 30w in...but wondering if 10w-30 would be better/
Thanks

I use 10W-30 year round in my two Bs, G and WD45

10-w-30 is your best bet. You need the 10 for winter startups to get the oil moving, and the 30wt is a good viscosity for summer use.

Depends on where you are. Here in Missouri I use 20W-50 in almost all my tractors cars trucks and even the lawn mower

I use Rotella 10w30 with Lucas oil stabilizer in my WD45.
