Hmmmm i'm using Syntium 1000 n to me its ok.. Used BP synthetic b4 n i found em not to my taste, the engine feels heavy and lazy..

im using Castrol 10W60, heavy, but rev hapily
mobil expensive loh

There is a reason for the price difference. Try lighter engine oils and it will even be more happy to rev.

I'm driving LMST.. I already REV above 4k rpm.. What engine oil is suitable? current I just using 10/40w semi synthetic oil. (bProton SC shop brand).

but u sure lighter engine oil xW40 wont damage my internal with rev around 7k? if yes, then i might wana try lighter oil
btw, from mineral oil changed to fully synthetic, do i really really ned to flush my engine?
coz when i change engine oil to fully synthetic, i dont see my mech flushing my engine oil.. then i ask him n he said forgotten
but he claim that it is ok... abit scared now

4k~5k is normal.. try above 6k~7k since ur engine oil is light
btw, proton SC use Shell if not wrong

I rev till 7k, even on 4th gear, and no problems. You're not the only one who revs that high. As for flush, they are not recommended as they leave behind harsh chemicals that's not good for the engine. There is no need to flush at all if the engine oil is changed every 3 months or 5000km.

Rev above 6k-7k? 4g13p can take this 6k-7k rpm? Hehe..

Probably, they give u Shell Super only, which is a multigrade mineral oil.

I saw another forum, they all recommend Mobil,

For me, I just don't wan cheap oil, n not heavy....any recommendation?

I rev high once in a while, maybe once a week, or twice a month to maintain the power.....

I prefer better torque...any idea?

i'm using Q8.. its kinda not bad.. silent engine, response etc.
the only thing is that the price is increasing quite rapidly,
n also its kinda hard to source for it.. only few shops are selling it..

Wat brand? Mobil?

The brand is called Q8. Top of their line is called Q8 Formula 1. Yes, it is getting difficult to source as it is expensive and not very well known here. My workshop still has a source for it.

thanks for the explanation
i've also managed to find a source for it..
recommendable, except for the hiking in price and difficulty in sourcing

my suggestion is castrol syntec 0w-30 @/aka German Castrol
very good fully synthetic grade IV + V oils.

where to get it
i get it from here
http://www.myoilstore.com

why not? 4G13 can take up to 6.5k rpm

if u got the cash, juz go for redline/motul/Q8 etc

AMSOIL (not to be confused with Amoil) is the first company to come up with fully synthetic oil. That's what they boldly claim and no one dare to sue them or using the tagline "1st in synthetic"

I'm using AMSOIL ATM with 10W/30 grade..they have pretty diverse viscosity grade in their product lineup.

So far so good, won't return to mineral oil again.

I mail ordered from http://www.myoilstore.com too..

My foreman told me that my car(Satria GTI) cannot use Fully Sync, can use Mineral/Semi-sync only, -.-" anymore recommendation?

dude, take a look here
http://www.schaefferoil.com/datapdf/705.pdf
this 20W50 which is highest grade among its product line also given the name 'racing', juz like castrol EDGE 'SPORT'

Marketing. Why don't you check the oils from the largest Petroleum companies and they do not need to associate themselves with 'racing' or 'sports'. Well, at least I know that their marketing strategies are working on you.

Is it recommended to use semi-synthetic first instead of a direct jump to fully synthetic? I'm not sure, this is what I read somewhere...
