What brand of oil and gas octane?

Rnroutlaw · #1 11-16-2008, 04:08 PM

The excitement is too much for me! So how about another post....What brand of oil are some of you using that you think have given you a slight performance increase of any type? And how about gasoline octane? should I just use 87 octane and a cheap brand oil while breaking the motor in or will it be ok to use quality supplies right out of the box? Thanks.....1 more day till package arrives!!!!!!

Buy the best synthetic you can! It will last you months and burns clean with no smoke or smell. I used the Amsoil but make sure it's not the ejection type.
I went for well over year of trouble free driving. I used 1 1/2 oz per litre to stay on the safe side. I read a good article about the newer fuels with bio fuels added hurting engines so try to stay with "normal gasoline". I think the story I read was from a snowmobile manufacturer. Search out and read up on "breaking engine in" on this site, it's very important. Lots of smooth slow to fast drives, letting engine build up speed at a nice smooth pace lets the piston rings wear in nicely. I went with two ozs per litre for my first tank of gas.

I run Poulan Synthetic......or Penzoil for Air Cooled Engines. In fact I'm getting a case of the later next week.

Any good quality synthetic will do. I use Valvoline. Do NOT use outboard 2-stroke oil.

There's no reason to go any higher octane than the lowest available (85 or 87 depending on where you are).

Because most gas has ethanol in it now, only mix up a gallon or less at a time. You don't want to leave your premix sitting around for a long time (crap, there goes that gallon I mixed last month the day before my motor blew.)

Valvoline is great 2 stroke oil. Another great Choice is AMSoil interceptor from Pablo. Enjoy the ride..

I did this on accident with my first new build. What will happen if you use the outboard oil? I've had it running one time so far but it was dying going up hill or when I released the clutch. Also it was leaking black watery stuff from what seemed to be the head gasket. My oil and mixture are both blue, but it couldn't have been from using too much black grease somewhere could it? How would it get all the way up there? Is that related to using the outboard oil?

The outboard oil should be fine as long as it is 2 stroke oil and you are using the right mixture. No less then 20:1 on the new motor. The black stuff you are seeing around the head gasket is oil. That is the way it would look after it is burnt. Sounds to me like your head bolts are loose. Check them, and if you don't have a torque wrench snug them up but don't over tighten.

Yea that's what I thought. I had torqued them to 12lbs but it was a few days earlier. When I came home I tightened them too much and stripped an acorn nut. I ordered all new parts and reassembled it. I have yet to try running it yet. I still need to find a throttle because mine broke. The first time I used a break lever but it bent the cable a bit. It's good to know about the outboard oil. I am not sure actually which one it was because they are right next to each other on the shelf (same brand and color bottle at walmart. I'm going to try it again today after getting an o-ring for the carb and changing the pin position from 2 from top to 2 from bottom. Thanks
