First couple hundred miles on this oil and I can tell a significant difference in the engines drive ability. Would highly recommend this oil.

helps keep my engine cooler and im able to push my engine even harder than before. it helped my fuel millage. and cleaner burning engine.

the best oil I used ever for my trucks driving over 20,000 miles without adding any oil to the engine until next oil change

It’s a shame that I can buy this cheaper at Walmart than at Sam’s , it make no sense to pay a membership fee to waste my hard earned money 💰

Even though it may no longer carry gasoline certifications, T5 10W30 works very well in my outdoor power equipment.

Availability and great shipping time

Love the way it preform for my DURAMAX! It the best oil for my engine!

I have a 40 yr old John Deere tractor is this oil work for that ?

By far the best 15w-40 out there I recommend this to all my friends and families

Amazing oil to keep your turbo engine top notch even if its not a deisel
