Hi all, I’m not very knowledgeable on car stuff so please bear with me.
So I just bought my first ever GM product, an 08 Yukon xl Denali 2WD with 123,000 km on it a couple days ago - I come from blessed Toyota lands... I plan on using the truck only once or twice a week.
Yesterday I took it for a trip (total 230 km) and ended up with an average economy of 4.2 km/liter. I need to know if that is average or not? Seems excessive to me. How does a tune work exactly and should I go for it?
The drive the entire way in the highway was perfectly comfortable and smooth.
Some Issues: engine mounts are no good and leaks from pan and rear main seal. Also when the car idles, I can feel misfire. I poured a bottle of STP fuel system cleaner before my trip but it didn’t do squat to help it. Should I check the plugs or what?
PS: bought the car for roughly $4700 if you were wondering and I’m in the Middle East.
