Fuel additives and Octane booster
Greetings,
Is there anyone out the that's heard of or had any problems running fuel additives or octane boosters? I'd like to put in some injector cleaner, but was wondering what, if any, was being used by you all. Also, what octane does everyone run at? Thanks, Jason :cool: |
For N/A motors, the lowest octane is best. If you run boost from a turbo or supercharger, use the highest octane available. Octane is a measure of a fuels resistance to combustion. Since the combustion chamber is long in a rotary engine (as compared to a piston engine) you want a fuel that will burn quicker and spread the combustion throughout the chamber. The motor was designed with 2 spark plugs to assist in this. So a lower octane(faster burning fuel) is better for N/A motors.
For boosted motors, a higher octane is better because it is less resistant to detonation from compression. A turbo motor has lower compression than a N/A motor, but the air is compressed more from the turbo, which raises the over all compression of the air/fuel mixture. lower octane fuels will ignite prematurely from the compression. This is called detonation, which is harmful to the engine. So, raising the octane of the fuel in a N/A motor has no benefit. And I don't have an answer to your fuel injector cleaner question. I haven't heard of any specific cleaner required. The fuel injector principle is the same on rotaries as it is on piston engines. The only difference is the internal engine components. You'll find that a lot of external stuff like the water pump, alternator, and starter all work the same was as on other motors. |
K, thanks. I'm going to using Gumout fuel injector clear/fuel additive.
Since I'm running a 88 TII what would be the recommended daily driving octane? |

and just another point, on a less technical note ... also buy it from a station that has some sort of reputation.
i.e. Shell, Mobil, 76, etc. vs. Bob's Gas and Giggle, Pam's Pump, etc. ;) |
pam's pump :rofl: Could be Pump Pam. Theirs places in the Midwest called Kum N Go.

Has anyone tried Marvel Mystery Oil top end lube fuel additive?? I think it's actually an oil additive that can be added to fuel to lube top end or in out case, the housings. Just thought I'd ask.

yes MMO is a common product for us.
