Valvoline VV171 Premium Conventional SAE 50 Motor Oil , 1 Quart Review

Customer Ratings:

I purchased Valvoline VV171 Premium Conventional SAE 50W Motor Oil

for my restored 1965 John Deere 3020 Diesel Tractor,

I had been using John Deere brand 15-40 Diesel Motor Oil since the engine overhaul,

it puffed blue smoke for the first 15 minutes after start-up,

since this tractor only runs is shows I change the oil and filter after every show,

the tractor no longer puffs any blue smoke and the engine runs much smoother and is nice and quiet.

Highly Recommended!
