i have a question. please guide me
i have corolla GLi, 185ooo odo. no oil reduction but i feel roughness in engine plus noise. i am using toyota 20-50 engine oil
Gear is also getting abit harder to shift in 1st and 2nd gear.
i want to use Liqui Moly products. suggest me following
1- Engine Oil (guide also if changing grade can b a problem or not)
2- Ceratec should be used or not in engine
3- Gear additive.
Help would be highly appreciated
