just bought 5w-30 from shell and wonder whether our proton saga is suit to use this grade ? as due to it is lighter oil compared to 10w40 and may improve on FC
Hi & Good morning, Everybody!!
Hi Bro niterider...
EOs fr xW30 to xW50 are all suitable for use in Gagas in our climate...
As long as the EO fulfills the SAE grades & API classifications...
However, as previously mentioned/posted, choice of EO shld b made rationally & with one knowing the consequences of one's choice & decision...
Thinner EOs allow better oil flow in cold conditions & an easier revving engine...
Thus there are claims of slightly lower FC...but feel kinda insignificant gains...butt dyno?
However, there's alwaz the other side of the coin...in long term & also depending on usage.
Higher wear & tear on all moving engine parts.
That's why most use xW40 which is the
middle road...
So over2yu, Bro...
Yr car, yr $$$, yr choice, your decision...
As in everything in Life!
Most importantly, be Happy...enjoy yr Gaga!
