I was hoping Indydan or someone would share their opinion of semi synthetic oil. I just put a new motor in my KingCat and sadly I have already done 2 heat cycles on torco semi-synth. Im gonna drain it out and run something else anyways(I have had lots of connecting rod bearing problems) and it sounds as though synthetic may be contributing to this. I have also noticed the corrosion/rust in my dirt bikes, my YZ125 has alway got synthetic, when I tore it down(for con rod, of course) it had light rust all over the crank/con rod. My KX250 that gets whatever is laying around, and is stored the same as my 125 has had no rust on the crank..... I do prefer how my bikes run on synthetic, and I dont care much about rebuilding them. The 900 is another story though. Thanks for any opinions!
Buddy........You answered all your own questions in your post.
Run what your wallet tells you to run..............Not what your dealers & oil salesman tell you to run.
** Note ** To all, Most oil salesman no less about oil then anyone. what they do know........ is what the paper works says in the dealer kit they got with their first big order.
Amsoil patented this tactic. as I said and will continue to say.
Run what your wallet tells you to run.
don't get me wrong......There is a time a place for synthetics
NUMBER ONE - COLD COLD COLD COLD WEATHER!!!! cold starts in diesels
there is NOTHING better then a good synthetic. if you don't start it in the old run the cheap stuff.
as for the sled motors.........Run the cheap stuff.
Castrol T2
injex - the cheap stuff.
there are many more forsale
fleetfarm, tractor supply, walmart the list goes on and on.
save your oil money for the fuel tank - Good gas is whats hard to find.
a blend is better then straight syn, but I prefer straight mineral oil.
TCW3/Jasco rated.
the exhaust valves will be just fine.
Indydan is this the oil you run?

Dan,
Not to beat a dead horse.
What I'm getting from this thread concerning the oil is this:
Switch to a good petroleum based oil AND add 1 pint of the same oil to each tank of GOOD gas. Then keep your exhaust valves clean.
Does this cover it? YES IN MY OPINION>
Thanks.
More sled motors have been ruined by bad gas, then will ever be ruined by any oil.
Thats the stuff!!!!
Its cheap and its great oil.
John Force would be proud.
How much are you guys paying for that castrol oil? And where are you finding it at?
Good luck finding it. I called Castrol to find a place in Ohio that sells it, and they gave me their distributors number (KK motorcycle Supply), and they don't carry it
Can you buy it online?
i just buy it at any old gas station up here in MT. Napa has it too
