125-200cc Amsoil interceptor oil

I have been using this for a while now at 32:1 in my wr150 with good results-little spooge,smoke. I recently replaced the stock pipe with a fmf fatty and I took a look at the piston and cylinder while I had the pipe off. I am very impressed with the cleanliness of this oil,I had a look at things before when I was running other oil(yamalube,motul)and there was residue on the power-valves and piston crown. Now every-thing is very clean and has a nice coating of oil on it. I know every-one has opinions on what oil they like and what they think works best, but I just wanted to put this out there. It's good stuff.

I agree, its mainly what I've run in my husky 125's for over 4 years. Never much build up on PV's or piston crowns. I also like castor 927, although its only the other people I ride with that benefit from the smell.

Yep it's very good oil. I run their Dominator with the same results for years.

Yep Intercepter works for me.

What is the difference between Dominator and Interceptor?

Actually Dominator has the higher flashpoint of the two. I've been mixing Interceptor and Dominator but once I run out of Dominator I will probably use Interceptor from then on. I think Interceptor has more corrosion protection then Dominator. Dominator is more for the hardcore racer that is running it harder and frequently inspecting his engine. I don't think there is a better oil than either one of them especially if you are running race fuel.

Here is a shot of my 125 piston after 88.7 hours of Klotz R50.



Here is that same piston 55 hours of amsoil interceptor later, the last 26.4 of those were with the lectron. Something is running much cleaner... not sure if I attribute it to the oil or the carb. Overall I think the piston looks good for a 125 with 143.7 hours on it.



Later,

One other factor with piston crown deposits is jetting. Lean, hotter running jetting will cause more carbon buildup on the piston crown, while richer jetting will give more "piston wash" or less build up. Although I think that the solvent in some oils keeps the piston cleaner regardless.

That's weird jmetteer I have had the exact opposite results with r50 that's the only thing I will run and I run it at 50:1

I only swapped because I was having an issue fouling plugs, that ended up being low compression. I stayed with amsoil based on cost, it is about half the cost of R50. I run both oils at 32:1 in my 125, it spends some time at high rpm so I like the extra protection.

Later,

That's not a real good way to compair then

I've never had any oil foul plugs, it's all jetting.

I'm sure he is a great guy (he rides a husky) but having running issues on a piston well past its life span I didn't think was a good way to compair it is awesome to get 88 hrs out of a 125 I don't know any other brands that get that

That's not a real good way to spell compare

Lol that why I fix things for a living not teach. I use my cell phone for this forum I should make more mistakes then I do using a tiny screen.
