I'm sure jealous of that collection. I burnt my last bit of MX2T/2R a long time ago.as a hardcore 2 stroke dirt bike guy I can say that Motul 800 is good stuff. another great oil is Champion WP. my riding bud put 255 hours on his KTM 300XC with it and when I did a top end for him everything was perfect. not a mark. he's been using it for 25 years. I use this and have had fantastic results.

It was a remarkable oil that only cost $3.50 a pint!
