does it sound more like a knocking sound from the engine at idle?
Run a tank of high octane through it or add a bottle of octane boost, I did this 4 months ago and have been able to run 87 octane in it and the ping has not returned yet.
your engine is craving a higher octane fuel, run a tank of premium or use a bottle of octane boost every now and then and that should satisfy it for a while.
yes
No reason to use it. It does not increase power output. Mowers are designed to run on regular octane gas, and do not need higher octane numbers.
unless the vehicle manufacturers instructions specifically state to use high octane fuel, or you have done something to boost the compression ratio, (i.e. supercharger, turbocharger, etc,...) you should be fine running regular 87 octane.
put more in or get a new car
Yes I was told it can boost you octane level.
Low octane fuel. Run a tank of premium through it or add a bottle of octane boost and it will be fine for a while.
You can put controlling heat is so much harder. Usually on a high compression engine you want to run less boost. You can also get away with running more boost if you go with higher octane gas. This will help control heat and fight detonation. Thank you, From www.SuperchargersOnline.com
the engine is knockinq due to low octane fuel. try a tank of higher octane or add some octane boost to what you now have and it should be good for a while.
Maybe but most times it is due to cheap gas with low octane. Try some octane boost or a tank of Premium.
Yes, any engine can be turbocharged. How much boost it can handle depends on, 1. the strength of the internal parts/ block 2. the fuel octane/compression your are running 3. size of the turbo/turboes being used.
