Great oil good price

I've used bel-ray in my two stokes and in my four strokes and cant say ive ever seen or smelled anything bad about them. The 10-40 holds up well in the florida heat.

Bel-ray products

I have used Bel-ray products since the 80’s and haven’t been let down. The Thumper Racing Synthetic oil works great and is affordable.

Good oil

Can't tell a difference between this and the almost twice as expensive amsoil I've always used. This will be my oil from now on

Great Oil

I use this is my 15 CRF250R, and is working great. No issues with bike, the jug has a built in spout in the lid which makes pouring into a funnel that much easier.

Bel Ray oil.

Great oil at a good price. Works great in my kx250f. I also use Bel Ray gear saver oil in my 2 stroke

All I use in my Honda CRF450R

One of the Best Oils you can use, also when I switched to a 4 stroke bike back in 05 I contacted BelRay and spoke with John. We went over the oils for my new bike as I was a 4 stroke virgin and since I have used BelRay ever since I was a kid I stick with it. They are spot on offer great sound advice and support. When we tore my engine down the first time ever the guys in the shop thought it had been torn down and all new internals. That was at the 9 year age of my bike.

A: For your 2008 Honda CRF150R this 4T 10W-40 will work great in the motor but for the transmission the Bel-Ray Gear Saver 80wt would be recommended. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.
