Comments about Pennzoil Heavy-duty Multigrade 4-cycle Engine Oil, Sae 15w-40, Gallon:

No other motor oil even comes close. Thank you Pennzoil for keeping mine and my family's engines cleaner and running longer for as long as I can remember. It's no wonder Pennzoil is America's #1 brand of motor oil. You have a lifelong customer in me.

Comments about Pennzoil Heavy-duty Multigrade 4-cycle Engine Oil, Sae 15w-40, Gallon:

I purchased a new Honda Civic in 1994, I would changed the oil every 3,000-5,000 miles. Advance 23 yrs later and 385,000 miles later I still have the same car, same engine, and it does not burn oil

A relative used this(not the racing version) is his Chev V8, straight 30w, when he set a drag racing class world record. He says it never let him down. That's good enough for me too!
