Buy a 45 thousand dollar car and pinch a few pennies.

Love that my Costco has 93 octane at the 91 octane price anywhere else.


From the Owner's Manual:

Octane rating
Volvo requires premium fuel (91 octane or higher) for all T5, T6 and T8 engines, and recommends AKI 93 for optimal performance and fuel economy. See decal examples in illustrations 1 and 2.
For optimal performance, Volvo recommends premium fuel (91 octane and higher) for T4 engines. However, engine reliability should not be affected as long as 87 octane or higher is used. See decal example in illustration 3.

 

Looking at the lists, Edmunds is suggesting the T5 engine "recommends" 91+ while the T6/T8 engine "requires" 91+. As jayman stated, the manual says otherwise. Go with the manual.

Is your T5 going to detonate on 87 octane? No, but it probably won't run well at high load and your fuel economy will decrease because the engine is pulling ignition timing.

 

Here we go again.

 

And again...and again...

 

Octane requirements are not based on how much the car is.

Here's a tip that is universal:
Read your owner's manual and do what it requires. Works every time on every car.

Edmunds probably made the mistake because originally the T5 Drive-E used regular 87 octane in 2015 and 2016. They probably didn’t realize the engine requirements changed for this engine to require premium.

I've had xc90 xc60 and xc40 and never once put premium and never once had any performance issues whatsoever.

 

Great. For everyone else, I'd suggest you do as the manual requires.

 

Is Edmunds a car company? Just checking to see if I missed something....
