Blue Marble--synthetic or mineral base?

[Adrenaline Revolution]

I was told by a Blue Marble Rep at a Sled how here in Wa. NOT to use the BM until I had at least 100 miles on the sled. He said to use what the Dealer recomends until then to properly seat the rings and when you change over to BM to suck out the remaining old oil from your tank before adding the BM, NOT to mix it as the benefits you get from BM will start being noticeable sooner.
It's all I have run for years now in our last 4 sleds with absolutely zero problems.
Someone mentioned the "Coating" that BM adds to the internals earlier to fight oxidation and it's true. I have torn down my engines now and then for some mods, not problems and I noticed the inside of the motor is pefectly spotless. I can still see the cross hatch pattern on the cylinders after many miles, they look like new!

I don't ever fog my motors prior to summer and have never seen moisture or corrosion to be an issue.

The only downside I have noticed or heard of is not being able to read any piston wash. there isn't anything to see. Exhaust valves stay spotless.

Due to this thread I was curious about trying it so I called the local snowmobile shop to ask if they sell BM. The guy reluctantly said "yes" but that hes going to discontinue selling it. He was torn between wanting the remaining stock sold and trying to sell something "better". He went off on how ****ty of an oil it was and problems hes had with machines running it and how much better pure synths are. This highly contrasts to what Indydan said in his thread and I'm more apt to believe indydan than the local shop.

I still dunno what I want to run in the sled I jsut bought. Its always been on amsoil but I want to run something else.

I ran BM for over a season. I will not ever run it in my sled again, I used it in my leafblower to finish it off....then the leafblower siezed! I have never seen the corrosion in a sled engine/pipe that I had with BM. I also didn't like the fact the internals were so "clean"....a oil can't protect if it isn't present!! I will stick with cheap petroleum oil, never a problem.

funny how its seems like hit or miss with this stuff, its either "im never going back", or "im never using again"...

No biggie, It just works faster if it isn't diluted.




Some times, I guess, some folks have had issues with BM but the vast majority of folks have had excellent results with it.

Within the sledding comunity, we are talking about a huge number of two stroke motors, which if you think about it are a pretty high performing motor being revved to the max for extended periods in extreme conditions.
You are going to have quite a few of those motors squeak for various reasons.
Are these blown motors the direct result of the oil or could it also be jetting, miles, gas, temps, improper manufaturing, bad set-up or just plain abuse.....It's hard to say that a few bad experiences are linked directly to the oil. Ther are so many other factors to consider but if an already weak or questionable motor squeaks right after starting to use a different oil it's pretty easy to point your finger at the oil and not the real culprit.

I have no reason to use a different oil until I have proof that there is a better product than BM.

Ok, so we all know that 2 stroke oil is cut with something to make it mix well and flow at low temperatures.
I am not sure what it is cut with(kerosene?) My thought is BM has a higher concentration of this which makes it keep everything cleaner. Problem is there is less of the important stuff. Some people have no issues because their pump is turned up a bit more.

This is my theory, and does not include any facts.


What is it IndyDan said? If I remember correctly it was use the cheapest oil you can find.
I know why, but I can't bring myself to do it.

i live life by the "reasonable man theory"....if half the guys here say "i'll never go back" and half say "never again"....i say there are much better options. personally i have run torco sso for 9 years. never a problem. clean valves after 1200 miles this year. no hype from them. no BS about molecular bonding. take poll and see if anyone on here has squeaked a motor using it....i doubt it. mobil does make a 2 stroke oil.......and you will have a stroke at the price. they don't seem to market it with the "high volume" user in mind. more like lawn mowers, etc.... sure it is great stuff. regarding BM's advice not too use during break-in....not unusual with any synthetic either.....harley specifically prohibits using syn oil due to the flat-spotting of roller bearings in overhead cams using syn's. any oil that has HUGE promo (i.e. klotz, amsoil, BM) and many "converted" disciples, automatically makes me suspicious. my experience with poo VES is it carboned up my valves bad. not here to sell my preference....just to wave the BS flag when needed. [:-}

 

[Insaneboltrounder/sjohns]

I still think BM is BS. They make claims i know are Krap. NOTHING bonds to metal surfaces , they have made so many bogus claims i will never buy their ****t. Lie like that and suffer the results.

 

[carguy]

Anyone ever use VP Fuel C2 synthetic 2 stroke oil?

 

[Rmk/lolos]

I used it last year in my sled,my exhaust valves kept sticking took them apart and cleaned them was told it was because of bm went back to ves havent had any problems.

(when in doubt throttle out)

[cmantle1]

all they guys i ride with use it in thier doos, and they have had good luck, so i decided to do it. its cheaper than doo oil, which is the only other thing i run. i have heard plenty of bad things, but good things too. just curious did any other guys on here running BM turn up thier jetting?

I run it in all of my sleds with great results but the turbo went in my Volkswagen. Damn Blue Marble...lol
