I've used bel-ray many years ago & it always done a good job for me. The reason I chose it again is because I think it has helped clean the power valve in my cr250r. And the guys at Motorsport has been very good at exchanging the other oils that I have tried. I'll be back for more.

I use at 80:1 mix for my Gas Gas 250 trials bike. Nice smooth throttle response and clean burning.
I was using castor 927 at 32:1 and I had a pining noise in there I didn't like. So I got this stuff mixed it at 32:1 or a little more and the tinging went away and it made the bike alot more responsive so this is my new go too oil. Oh and it was my 2003 ktm 125sx
I use this on my 2001 cr250, I trail ride so I need to mix it at 40:1. There is alot of smoke at first but once the bike is warmed up there is almost none. I would recommend buying the 1 liter bottle. 1 liter is 33.8 ounces, a 40:1 ratio requires 3.2 ounces of oil per gallon. So it gives me about 10 gallons of gas which is WELL worth it! I was thinking about switching to the cheaper Honda HP2 oil but I just don't want to screw up anything motor wise transitioning from the two different oils.
I've been using this in my 01 KX 250 since I bought it in 2011. There have been no problems with this oil. I mix it at 40:1 with proper jetting 92 octane. No powervalve issues either, operates like it should.
used for years at 40/1 versus stick 32/1 long engine life
New bottle has an overcomplicated cap - almost hate it
I have used all oils out there and this is the best by far. 40/1 in my cr250 and It burns perfect and makes no exhaust residue. Its red which helps to be able to see in your can that you have mixed it. It does need to be shook up very well in the can to mix with the gas but it never separates once mixed. It smells ok when burned but there's definitely better smelling mix out there.
I have used H1R for 10 years and have had no problems what so ever !
We use H1R mostly because the power valve on the YZ 125 doesn't get nearly as crusted up when we use it and makes cleaning the valve (still part of our regular prep) a quick/easy.
