Well,i keep regular maintenance. I've owned 2 corollas, gli MT both:
1. Total Parco 9000 5w30 with drain interval of 6000-7000 km, depends ( local oil filters don't go above 7000 )
2. Fuel only from Total Parco pumps. I've experimented with different pumps in Johar town with different cars and found that Total Parco near LDA and Rahat Bakery are better than PSO and Shell.
2. I have air filter cleaned by air 2 times and replaced on third time when i go to do any type of servicing ( oil change, tuning etc)
3. My mechanic ( Adil workshop, next to Suzuki Township) is very experienced and used to work in Suzuki after service. He advised tuning on 17,000 km in one corolla. The car had lost acceleration and fuel avg dropped to 11.5 with AC. In tuning, he cleaned plugs wagaira and did throttle servicing and filter cleaning and hooked up OBD bluetooth to the car. He adjusted wires and screws on the engine head (camshaft, or as we call it, tappets) The rpms and air fuel mixture came up on his laptop. He set all the rpms, and accelerator became better than before and fuel average went back upto 13 kml. The same can be said for my Mehran. The total cost was rs 1500.
4. I check all fluid levels in my cars every week, and do some stuff on my own. In order to attain good gas mileage, it is very necessary to have an understanding of how your engine works and preforms best at, that way, the engine lasts longer, produces a bit more power, and gives better economy.
5. I tend to apply some methods used by professionanal racers into daily driving, such as proper downshifiting, heel-toe, and knowing when to brake and accelerate. This way, my driving is a bit more efficient.
Note: both corollas are used mainly for long routes, mostly to Bahawalnagar, where the road is very bumpy and the air has alot of dust in it.
