Regular Gasoline in 2.4l?[ALL/1998] posted by Tony Zee on

I just got an S70 last weekend with the standard 5 cyl engine. I thought I would try the first refill with regular unleaded gasoline (87). Works great.

Is there any sense in fueling the car with higher octane gasoline?

Thanks & regards,

Tony, From all the stuff that I've read and all I've seen on reports on octane levels, It makes no difference! If you use 87 or 94 octane. Some say the higher the octane level the more the performance level on your car! The car manfactures recommend that you use the more higher octane fuel because your are paying a more high price for their better cars. I've been told that the high octane fuel has more better cleaning addatives than the lower octane gasoline. I'm still waiting the verdit on that topic! Remember! Buyer Beware, you get what you pay for!

An engine designed to run on high octane gas won't run well on low octane gas. But if your engine is designed to run on low octane gas, then using high octane gas only affects your wallet.

Nowadays all new cars sold in Finland run on 95 RON octane gas, only some older high-compression engines, like the B230A on my '86 Volvo 740, require 98 octane gas.

The car runs better with higher octane, but if you want to use lower octane you should adjust the ignition system accordingly. Then it sould be OK, also with the fuel consumption.
