Patinum Spark Plugs And High Octane Gas?

[rodf]

Howdy All,

2 questions if I may...

1. Is it worth putting platinum spark plugs in a 40hp Yamaha (2007 model, 3 cylinder) ...and

2. Is it worth using high octane petrol?

Cheers,

Rod

I personaly wouldn't waste yer money on fancy plugs, it's better to change them more regular so you end up with fresh plugs more often for yer money.

I usally top up fuel with 95- 96 octane or complete fill with normal unleaded, there is no advantage using 98 octane, the compression ratio is not high enough, stay away from ethonal type fuels

I usally filled with premium fuels 95 octane

so that if the fuel is not used as quick the octane level may drop but only drops to a lower level.

not start at 91 then drop into the 80,s

well thats my take and idea on it

Plug i would say use what is needed for your motor and have a back up set so if you have a foul up you can get out of the situation
