if it is the OS #8 glow plug, then you may be in trouble. its too short for the engine, causing it to run very lean or be horribly out of tune. and i think 15% is a little too low. you should stick with 20% next time.

Yeah, 20% is actually recommended in XTM's instructions, and they also recommend either Trinity Monster Horsepower Fuel or XTM's fuel. However, any fuel, basically, with oil content that is between 10%-14% should be ok without giving you too much one-way bearing problems. I ran Blue Thunder and it gave me an extremem amount of one-way bearing problems in my PS. I really don't wanna experiment with fuel and I don't suggest experimenting because it's hard to get the truck running in the first place. I don't see how you would put that hard work to waste by experimenting w/fuels. Just my 2 cents though.

steven, it doesnt matter what oil percentage they recommend. words in a manual are just plain JIBBERISH. i mean come on, who reads the manual these days? only thing i use my manual for is for looking at the exploded diagram of the car. i doubt that the OWB was the blue thunder's fault. as long as your fuel is meant for cars, put it in. O'Donnell, Blue Thunder, White Lightning (eh), Traxxas Top Fuel, Sidewinder, Byrons, Trinity or any other ones are fine. as long as you know how to tune an engine and listen to other people's favorite brand, you are alright i personally would go with O'Donnell, just because it runs pretty cool and has explosive accelaration. did i mention that it smells good too? . this is my $200,000, not my two pennies

I don't know what to tell you Aznracer accept, me personally, I'm not in the frame of mind with my truck to start experimenting now. I already have to rip it apart over the winter which will prolly take long enough, I don't need some faulty mistake tacking on another job to my list of upgrades that I have to do. I agree that I should try other stuff, but I've had my truck for a long time, most of that time was sitting because I was a noob and didin't know how to do stuff. Anway, as far as glow plugs go, I use a McCoy 59 and XTM glow plugs. I would really recommend the McCoy's because mine has lasted pretty long. If you didn't get a glow starter yet, here's the one I have: http://www.hobbypeople.net/gallery/146045.asp It has the meter and everything so you should be ok.

That's probably 2 days that I don't have time for. It just takes too long, that's why I'm saving it for winter. I could see me starting and then holding it off which will just get me ticked.

I've always run Top Fuel in my Revo. I know this is the Mammoth thread, but fuel is fuel. The oil % doesnt matter in ANY car/truck. All it does is, Less oil, less lubrication and More oil, more lubrication. If you race, you want less lubrication, if you bash you want more lubrication, but less is fine too. Simple as that. 18% oil is recommened for my Revo, since Top Fuel has 18%, but once I tried O'Donnel it was unbelieveable. My Revo gained so much power that it wouldn't stay on all 4 wheels, I had to ease off of throttle if i wanted to do a high speed run . Also, with O'Donnel my engine ran so much cooler that I had to lean it out, which added even more power. Now, since I run with ssj2, I know how high his temps get, sometimes in the 300s, and he runs Byrons/Trinity. I'm sure if he would give O'Donnel a try, his temps wouldn't cross the 280 line.

Like I said, I'm really not willing to experiment because if something goes wrong you guys aren't the ones who have to deal with it, I do. In XTM engines, they're made differently and you get a crap load of OWB problems with 18%, and if you check out the tips thread on XTM, BT gives you the "low-down" on what to use. Maybe I should check Odonnel's but right now I'm stuck with Byron's until I get done with my 2 gallons.

I'm not saying to try a fuel with 18%. I'm saying to use O'Donnel, which i don't even think has 12%. XTM engines are made "differently" if you know what I mean . Dude, you don't have to stick to one type of fuel because it is "recommended". You could try a different fuel, and if it doesn't work for you, then drop it.

Meanwhile, I've just spent how much for a gallon/quart of fuel to just "try"? Seems like that's throwing money away, I'd love to try it someday, but today is just not the day.

My problems aren't your guy's problems, try giving some people a break once in a while or you could just keep on beating the dead horse. I'm not gonna get into a flame war with you too, and I think this thead's now been ruined, too bad it was pretty good. Not everyone follows everyone else, I'm one of those people, and I like my fuel that I use, and XTM does use different metal while making their engines. Call what I'm doing what you want, I don't really care. Let's try to get back on topic here people.
