How's your car, any improvement? Please update.
I would like to share few more tips with you, based on my personal experience.
1-Always go for Total petrol, It give the best performance (pickup) & milage.
Every time I shifted to other brand (PSO, Shell, Caltex & Attock) the car just becomes lazy and milage drops.
If you really want to enjoy the performance of your car add 10 ltr of high octane with tank full of super from Total.
2-I use Total synthetic oil (Golden can) and drain it at 5000kms interval.
3-I change the oil filter every time. (I buy the oil filter from Toyota 3S)
4-I Change the air filter every 10,000/- kms. (I buy the air filter from Toyota 3S). Pls make sure you buy the air filter for Altis and not Corolla. Very few people know that the filters are different.
My car does 10.8 ~ 11km/ltr in city with air conditioner on always.I get hows your car doing.
