Dear All,
I have cultus 2008 efi and need experts OPINIONS to use best engine oil which is better for engine performance as well as the fuel economy.
Last time i had used Toyota multigrade API SL/CF 20W50. it is good but i want to change this time.
also confirm about the difference if i will use high grade oil like 20w50 OR low grade like 10w40 or 15w40. which grade is better for efi cultus (mileage around 100k)??
some oils which i know....
Shell helix hx5 10w40 or 15w40
Petromin ultra 20w50 (some ppl said it is thick oil??)
or toyota one as mentioned above
