I just read in the local Menard's insert they re having a sale this week on a gallon of that product's 10W-30 and 15W-40 for $9.99. The label says it's approved for Cummins diesel engines....I am a long-term user of Shell Rotella-T 15W-40 in my tractor and that costs about $13-14 per gallon. I will have to check to see if the advertised Valvoline meets the Deere specs for oil. Or would a member here know? Thank you.
