Ohh, my 45% balance means I assume between the High(100%) and low(0%), my lube stay at 45% between them at 5k...

Mayb I should try, and I duno the API thing for my car engine as well

Oh! then it is okay. 45% between dip stick high and low level is good......

Old car no need follow so closely the API. Oil now mostly SM, if not SL. Of course got some SJ and even the newest SN.
But if old car can still use SL and SM oil, no problem.

i mean the viscosity

if the fella drive 130y using fs he is damn rich

You should stick to mineral oil, unless you planning to overhaul the engine in recent times or if something goes wrong.

Mineral oil actually helped to close any gap caused by wears in all these time, changing to SS or FS will clean the deposits and resulting the thinner oil to leak out.

ha! ha! true also, but very few FS 20w-50......

Added on December 17, 2011, 8:17 pmNormally SS 10w-40 can still be used. SS are still mineral oil based. Even Group 3 Hydro Cracked FS are made from crude oil. Mineral oil have higher viscosity (thicker) that is why the blow by into the combustion chamber is less, not because it does not clean. SS is Mid viscosity, starts with 5w or 10w and FS the lightest at 0w.
If don't want to try SS 10w-40 still can try Mineral 15w-40 instead of 20w-50.
As mentioned if not good, can just switch back to 20w-50.

For my turbo, I did try 5w-30, found it too light so, after a week switch back to FS 5w-40.....my ride is a 1991 model.

For my wife's Sonata, was on FS 5w-40, then I switch to 5w-30 also can use and that is a 1996 model
Now on SS 10w-40 because cheaper and her car is NA so no need FS oil.....

Hi...
Do yu all know abt this?

"ExxonMobil recommends a five year maximum shelf-life for engine oils, including Mobil 1. "

Found this in Mobil FAQ here ==>
http://www.mobiloil.com/USA-English/MotorO...Shelf_Life.aspx

ps. This is probably reason why imported engine oil bottles (esp EU ones) hv manufacturing dates printed whereas our Msian ones do NOT hv!!!
As a result, we do NOT know how old is stock of oils we buy each time??

NB. Link corrected!!! Apologies...

Page not found??

Probably overseas needed by law but not here....

I see... I do agree that FS 20w 50 too hard to find in the market... Or I should say I've never seen any of them. Btw Castrol Modern Engine 15W 40 is Mineral oil right? Does brand also matter?

20w50 FS is quite common for the US market.. Try Amsoil .. Pretty good oil
