Used this in the last 2 oil changes in my 2018 crf250r and its dang good stuff! Made my bike run super smooth and even more crispy. This is all I will ever put in my bike!

Great product

I have run this in a couple for my bikes for a couple years now. When taking the motor apart for maintenance and such, signs of wear are minimal. I have had experience with Maxima oils. I run 15w50 in my 450 in warm weather and 10w40 in cooler weather.

Great oil

Bike has 100hrs on the hour meter now running this oil and Maximas reusable filter. Ive yet to have to touch the motor. Good Stuff!

Awesome oil and good insurance!

I run this in everything I own that requires service grade oil. I race a 2015 RMZ450 and it shifts great throughout the life of the oil. Maxima makes great products.

I also recommend Maxima's air filter oil!

Maxima Extra 4 10W-40

I contacted Maxima, this is what they recommended as the very best for my Kawi KLX 250s. Glad I found it on motosport!
