the maxima does work well. With the Castor/Benol oils, you need to be an A or AA rider. The ones that keep the gas pinned will benefit the most. I agree with running the synthetics for the average guys.

I have always tried to run company's products that I know support our sport the most. For years I ran the Klotz oils which worked well and smell the best IMO but mainly because they always had a support trailer at most of the races and would be title sponsor of some.

Times have changed now and other companies are stepping up and so has my oil choices. Don't know if there is any oil out of the big companies that is really better than the other, you just find what you like and want the best and run it. I just try to support the ones who support our passion to ride and race.

Same here. Great oil.

Am I the only guy using Opti-2

Motul 800, occasionally the 600 bikes and weed whacker since '99/'00.
Never had much of a spooge issue with it in my YZ250 [175hrs on last top end], but my 01 [GG] 250xc drips out of the silencer and exhaust connections.
50:1 ratio in both bikes and the weed whacker.

elf 2 xt 4,000 miles+ on my used gasgas and havent opened the engine yet!

I like Amsoil dominator. Works great for what I do.

I used to run Silkolene Comp2. Very good clean burning oil at 40:1 but they quit offering it in the gallon jugs, so I switched to Maxima Castor 927. Really like the smell of it until the next time I pulled the ex. off and realized how bad it carbons up everything.
Now I am running Maxima Formula K2 at 50:1. Seems to be a good clean burning oil. The only thing I don't like about it is its hard to tell if your gas has already been mixed or not. It just adds a real light brown color to the gas.

since nobody else seems to run it I'll mention I (we) use Royal Purple. I won a case of it 7rs ago and we've both been using it ever since. We had used Amsoil before that but this is easier for us to get.

I hope you are not still on the same case???

someone used a Motorex Cross Power?
have experience of using it in a ratio of 1 to 70 (100 ml to 7 liters)
I rode on it with the proportion is 48 hours. everything is in order)
