Octane rating for 260 hp. V70 base?

Is 87 okay for best/adequate performance?

could not find anything on Search!

Use the proper rating for your car or higher.

Do you know what your fuel management system senses a knock?

It adds extra fuel - because knocking is ignition BEFORE the plugs spark - changing timing may not work quickly.

I do not know if it resets itself normally - I found out during a trip across Canada when I got regular gas at a set of French pumps - I got 3 GPM less on that tankful!

What year is your car? A base 6 cylinder? Believe those started in 2008 with newer model V70 and XC70. The earlier cars had a base 5 cylinder with less HP. Plus a turbo engine.

My bad, it is a 168 hp and enquires 91 RON which by usa ratings = 87.
So "jwalker" is correct Shell will love it if you use their 93 which has less ethanol.
Thanks to both of you!

2000 V70 Owner's Manual specifies AKI 91 Octane.

91 AKI = 93 RON.

The AKI (Anti Knock Index) is the number that appears on the fuel pump in the United States, while the RON is the most common rating system used worldwide.

Confirm N/A 260hp?

Our 2000 V70 Owner's Manual specifies 91 Octane for the B5244S engine; N/A, 168hp, 10.3:1 compression ratio.

Lower octane fuel burns hotter. Have researched that White Block valves (four valves per cylinder) are susceptible to burning/failure with prolonged use of lower octane.

Our V70 just passed through 304K miles using 91. Still runs strong.

just use 93 for anti knock purposes

(Regret duplicate/multiple posts. Local internet connections are inconsistent today).

Doesn’t it say in your owner’s manual? Or check the fuel filler door. If no luck, call a Volvo dealer.

My guess is 89, but it will run ok on 87.
