hello, I've got a '03 corolla xli and was confused with some stuff, hope you could help me out!
1: what is the average I should get on petrol and cng in city with AC ?
2:which oil should I use?
3: which company spark plugs ?
4: should I get high octane and normal petrol mixed ? -what would be the benefit of doing so ?
5: car taking in a lot of water (coolant is what we call it probably)
6: should I get a cold air intake ? Benefit of getting it ?
7: recommended tyre size and company ?
8: alloys or not ? (i got this car 2-3months ago and had to get the suspension work done as according to a trusted mechanic the suspension was ruined due to the alloys.)
