AOA, need expertise opinion guys.
Im using TOYOTA original 20W50 PETRON oil since two years in my 2010 XLI (75000km) totally petrol driven, car is in excellent condition in every aspect.
But now i think why not to switch to any good oil available in the market like SHELL ultra 5W40 fully synthetic.
Is it wise to switch to fully synthetic oil from mineral oil, as i have heard that it can damage engine seals.
If not, then which oil u would like to recommend for my car? Thanks
