Can I use car oil to put in my gasoline for my engine? If not what do I use where can I get 93 gas?

mikmaxx,
Let us know what engine you are running. Car oil can't be used in a 2 stroke engine. It needs 2 stroke oil made for the purpose. Most engines (gasoline) don't need high octane fuel. If the engine is new most require oil specific to the break in purpose also.
EXCAP232

Go on line and find the instructions for your engine if you don't have them. Follow the instructions as to oil type, ratio mixture of oil to gas, octane and all will work as the designer intended.

I am using the gf45i crrc pro gasline engine and it doesnt say which oil to use in the manual. and the octane seems high is it al right to use lower?

I would buy the high octane gas. Look around for some Pennzoil air cooled or some AMSOIL.

Can I get High octane gas at the gas station?

Yeah, just buy the highest octane (premium) when you drive up to the pump. MVVS/Evolution says to run 95 octane in mine, but it does fine on the 91 we have here at the pumps in CO.

I have octane booster should I use it?

I have run lots of 2 stroke gas engines on chainsaws, weed -wackers, etc, etc. The small engines of today work well on 50 to one mix and thats all I use in any of them. Buy only oil from well known Manufacturers who make quality products.
I use the higher octane gas mixing a gal. at a time as it is usually a lot fresher and I also buy oil in containers that mix a gallon at a time so no mix-up on rates.
Auto oil is a very poor choice and has not been done for years.
I have had quite a number of large pro saws and they have all run well on good 50 to 1, working them as hard as I could in extreme heat.

PS: stay away from Penzoil it's pariffin based and turns to sludge in short order. It's the worst oil on the market in my view. A friend gave me some for my outboard and the exhaust was plugged with the worst sludge........I had hoped that the OB oil was better than the other , it was not. I burned the other containers in my oil stove.

Basically look for a good ashless oil. I know a guy that runs the Mercury Quicksilver in all his engines. I like synthetics. Since the bearings aren't the best in the MVVS engines, I'm planning on running a gallon or so AMSOIL Dominator through it and then maybe do a gallon of Pennzoil Air Cooled at 30:1 for a gallon to get a good ring seat. Then going back to AMSOIL.

Gizmo, were you running the Pennzoil Air Cooled in your outboard? That could be a problem as it is designed for air cooled engines and not water cooled. Back home we don't run anything but Quicksilver in our Mercury 115 or our 25 and 10 and we've never had problems. Oils can be funny.

Nope, it was Outboard oil for water cooled, it was in a Mercury 15 hp trolling engine. I usually use Merc. oil and only did six gallons with the Pennzoil(big mistake).

Yeah, I don't know how their TC-W3 is, but the Air Cooled stuff works pretty good for breaking in engines on the airplanes. I have a paper on it if you would like to read it.

Mik,

I use Mercury Quicksilver and 91 pump gas, these engines do not need high octane fuel, high octane fuel is used for high compression engines 17:1 and the like, higher octane may also make your aircooled engine run at a higher temp, I like Mercury's oil, there are a leader in 2 stroke technology and Quciksilver is TCW3 to help control carbon on the rings, its also approved for air cooled engines as stated on the bottle.


Good Luck,
Mike
