Salam everyone.
I’m using Hilux SR5 2011 as a daily driver but it is a little heavy on fuel. Currently giving around 5.5km/l with a/c. On average driving around 2000-2500 rpm. Got new spark plugs, air filter, changed fuel filter, oil filter and oil changed to Castrol 10-40 if I remember correctly as its driven around 130,000km. The only thing left is to get the catalytics checked.
Any tips to improve the fuel average would be very helpful.
Thanks!
