15304 SAE 5W30 Fully Synthetic Motor Oil - 1 Quart (6 Pack)

In every aspect of the transaction everything was exceptional!

As a mechanical engineer, i do have a tendency to research and get the best. Oil is the blood of an engine and should not be something you cheap on. Using this on a 2021 Civic Type R making 430+hp This oil is a true Ester5 based oil, and has the highest evaporative resistance of any oil out there. My catch can barely has 2-3 drops in the 12k+ miles i have put on since changing to this oil. By comparison, other people i know using other brands, have to empty their catch cans every few thousand miles. I religiously change the oil at 5k intervals or 6 months, whichever comes first.I pair this oil with a WIX filter. So far, i love the performance of this oil, and will not use anything else. Must have for those demanding the best oil.

I used this oil off a suggestion off you tube and this oil is the bomb!! Engine ran smoother and held strong over 10,000 miles.

Lo usé en mi Mustang Mach 1 2004, el auto tiene un tren de válvulas muy complejo que tiende a generar ruidos con los años y el desgaste, este aceite le sentó muuuy bien, no se notó inmediatamente si no con el paso de las millas, más que satisfecho y lo volveré a comprar.

After reading Ram truck and Hemi forums until my eyes bled, I decided to try Redline oil 5w30 and a Wix XP filter. All I can say is Wow! My Hemi had a slight tick and a noisy valve train when cold. Almost immediately after I changed the oil, it got quieter, I mean a lot quieter…and the engine runs soooo smooth. If you have the Hemi tick, try this. It’s pricey, yes, but man, what a difference. PS: going to 5w30 has not caused any issues with MDS, even in 14 degree weather.

It’s supposed to be the best for high performance motors

Excellent oil, expensive but worth it. It’s all I use.

One of the best
