I run Amsoil 2 stroke in everything. I have a few vintage bikes. I have been riding my 1992 Yamaha WR500 air cooled 2 stroke for the last handful of rides while I sort it out. Been good. No issues with it running wise but notice vintage 2 strokes usually recommend none synthetic oil at 20-24:1. Is there an issue running 32:1 amsoil full synthetic oil in these and if so why?
i run maxima full syn at 40:1 in everything .plus its easy to mix lol . one small energy drink can to 10 litres . half a bottle of 2 stroke to 20 litres . in the 80s the husky team ran full syn at 40:1 in the works bikes etc . good enough for me
Maybe some say that because they are air cooled but it doesn't make sense to me. I run 2/3 Dominator 1/3 Interceptor @ 40:1 in VP110 on everything 2 stroke I own chainsaws, leaf blowers, ect.
if it works well in your other bikes kelly i wouldnt hesitate running it in your air cooled bikes. like you i always have run 40:1 in all my bikes. good oil that works is good oil that works. im a castor man but i would have no problems running interceptor or dominator if i had to. perhaps if i ran my engines harder/longer i would run 32:1 but i have always had great life out of stuff..
I think the idea is caster oil is supposed to love hot spots and helps in hot running air cooled bikes. I have taken note that there is zero spooge on the WR500 using more oil in the fuel where my other bikes spooge like crazy with less oil. This leads me to believe the combustion and exhaust temps are a good bit higher on the airhammer. I;m sticking with my tried and true Amsoil right now but find the topic interesting.
I used Golden Spectro for decades. Lately after being told the formula has been changed I switched to Maxima. It does make spooge from the head pipe, but that is only due to my laziness to fix it with some chamber seal.
im a firm believer that spooge is directly related to jetting. sure, some oils are cleaner and some are dirtier but if its jetted right it wont spooge too bad. i really dont have spooge problems on any of my bikes running super techniplate which is castor/synthetic blend. smells awesome. i have ran it for almost 15 years and been inside plenty of my own engines as most of us have and im very happy with the protection, getting great longevity. that being said amsoil is good and that is what i would run if i abandoned castor. everyone talks about maxima castor, but not much talk about klotz on here. very quality oil, they are big into alternative fuels (methanol, alcohol) and state right on the bottle they blend easily with such. klotz does alot with rc planes and cars, which are probably harder on oil than anything
The castor oil also readily mixes with ethanol or methanol unlike some synthetics. I believe Ammsoil Dominator is not supposed to be used with ethanol or methanol fuels. I like ammsoil so much that I became a dealer for one year just so I could stock up with a four year supply for myself.... so far I haven't sold any to anyone but me.
I put a lick in my 4 bangers -probably 200 ish to 1 to lube top end and act as a valve cushion. iridiums dont foul either. Also acts as a fuel preserver.
I'm going to use maxima 927 castor mix next 20:1. Stock jetting unless I need to jet to it. I think the castor oil is the trick to longevity with cast iron sleeves. I use the b8es spark plugs so I don't hurt the SEM/motoplat igns. The castor oil functions better in the air cooled engines. Remember there is more heat in the AC engines. In my equipment the SEAFOAM is the best upper lube I have ever tested. It lubed the valves, frees stuck rings, reseats the rings, fuel stabilizer over the winter months, it's awesome.
When I was a kid in Idaho Klotz was popular for snowmobiles, so we basically used it in anything 2t including dirt bikes. Worked great and still does. A local parts shop now keeps it on the shelf in gallons at my request. Smells like the '70s to me My recent ol' racing bud always runs Maxima 927 in his YZs and that's what was available when I first got the Husky. Wow, that stuff really smells good, but at almost 2x the price wasn't worth it to me. At 40:1 I get @ 40 gl of mix from a gallon of Klotz, smells good, no fouling or excess spooge, engine seems happy. I think the 927 has a higher flash point than the Techniplate and that might be better for air heads, especially airhammers I remember there was a large contingent of Yamaha riders, especially after Hannah showed up, it seems they all swore by Yamalube claiming it was specifically formulated for YZs. The rest of us thought it was useless hype and I haven't ever used the stuff.
That's interesting, thanks. I've got a couple of lists comparing flashpoint temps and there seems to be some contradictions. Anyway, close enough. Would have thought the opposite for some reason.
i just got those from their respective manufacturer websites. either way, both are high. both will likely gum the motor up if not jetted right, but that goes for anything i guess. i have also ran the klotz last winter quite abit with little jetting change and it seemed stable. i lil splash in my mower works too! the chainsaw and weedeater have been living off the same 40:1 mix my bike sees for quite awhile. of course they are all husqvarnas too
I have been using Amsoil as no one chimed in why not to. Got a Lectron on it working amazing. Had the pipe off the other day, looked up the exhaust, looks shinny and new in there
amsoil will gum up if not jetted right as well, just like anything else. of course there is no reason to not use interceptor in any 2 stroke, air or liquid, regardless of age. the klotz flows in my lectron well too, all 4 seasons
My new husqvarna pro chainsaws have tighter tolerance so I only use husqvarna 2t oil. This husqvarna 2t is a good stabilizer too my saws sit for months then run awesome. The maxima 927 2t oil with the castor is what I'm going to use.
at 20:1? tighter tolerance than what? their older saws? their older xp saws? the husqvarna oil is good stuff, many use it. my father has used it years on his saws.
Yes than there older saws. There new 2t mix is for the newer saws I was advised by the dealer don't use any other 2t oil use only the husqvarna 2t saw oil. My three new saws ran ok but after the hit cutting 20 cords of firewood they really became more powerful. They needed break in time I guess. There animals now my 353, 575 @ 385 cut awesome.
the dealer is probably tired of cheapskates running bunk oil. my 87 was the same as your saws when it was new! was stiff and tight for full tank of fuel, then it suddenly seemed to really loosen up and start running better.
