Really depends on the rights leg. If highway and at national speed limits, i can get that fc figures or better, like 14km/l.once touched 14.5km/l which i mostly at highway and not speeding, and based on the center screen meter. If spirit driving, usually around 11.5km/l and usually drove it around 150 to 160kmh highway.

I usually filled up once there are b4 blinking. Hence usual the pump stop at around rm105 to 110. Only ron95 works for me.

Urs really jimat, Honda newer earth dreams engine really give more mileage per fuel tank. But ur tank size seems like much more smaller or u refill fuel b4 yellow light come out perhaps 🤔🤔.I drive jimat2 also can only get 12km/l, but meh, not feasible/practical for long term. Usual 2.4 accord I see, all pijak minyak on highway, me included. Hardly see people cruise relax2 sit on middle lane since this d segment car sedan is so damn stable at high speed. Lol.

Check your car manual, if listed, you can use xw20 oil without problem.

Petronas primax 95

Btw, dunno its pros and cons. Heavier car such as accord hard to drive slow on highway. No feel speed. Me always cruise at least 140kmh. Heard can get excellent fc if drive 110kmh, but seriously hard to cruise at 110kmh. Same goes to other heavy vehicle I believe.
