you guys should read the car/engine manual first. Theres a specific viscocity required for the type of weather/operating temperature you're in for optimum protection of the engine components.

Because he is using the wrong oil.
The correct oil for redline brand on the Sti should be Redline 75W90NS or Shockproof lightweight.

The motul 90PA is ok.

sumting to spice up this thread
price definitely dirt cheap, but quality wise not nuff promising
wad say u guys


Attached thumbnail(s)

The "Amerioil" brand of 20W-50 oil is quite lightweight
for its viscosity.

I bought one can from Univeral Auto in Pudu last time
and it improved performance in my "old junk" car.
Cost about $36 then, 4 liters.

However, they don't stock it anymore.

The agent is New Hoong Fatt, the importer of all those
Taiwan body parts. However, they are selling for about
$50 plus.

Universal Auto said they can sell much cheaper because
they order in bulk from New Hoong Fatt.


Other than than, Pennzoil's "MGMO' 20W-50 oil is also
not bad.

Usually use Mobil 1 or Castrol Edge 5W-30 for summer, 0W-40 winter. Tried Penrite SIN 0-50W once.. lightest oil they had in the SIN range, apparently ok as a 0W-40 replacement.. and my fuel consumption went down the drain.

mobil 1 5-50w so far so good ... engine oil gets dirty very quick..alot cleansing of engine

Castrol Edge 10-60w, 3SGTE with 300+ hp

Thanks for the feedback! What does NS mean behind the viscosity index?

The NS is not part of the viscosity index. The NS belongs to redline. The viscosity index should read as Redline 75W90 NS. Notice the space between the 90 and NS.

For redline, the NS series of gear oils do not contain any friction modifiers. Normal synthetic gear oils are too slippery for LSDs. The NS series are made specifically for gearboxs with LSDs.

Oil Type & Grade : Heavy Duty Engine Oil, 15W-40 API CI-4/SL
Price : RM65 / 5L
Feedback : Engine run smoothly and great for my usual 6 month OCI (Between 3000 ~ 8000+ KM) but sounded coarser after 4 ~ 5 month of usage)

anyone used that Motul H-Tech 5w30 before on a campro? how's it?

never tried motul, but using redline 5w-30 on campro after some time will hear tak tak tak sound from camshaft..

hm..too thin?

5W-30 is ok, not too thin, but I think 5W-40 would be best, catter for low and high temperature. You need the flow of thin oil during cold for easier pumping around the engine for protection, if you rev high, then you might need the higher viscosity to avoid oil lost.

Since shinjite said Campro is hot, I'll recommend you to go with 5W-40 or 10W-40. 5W-30 would be ok too but monitor oil level every once or 2 weeks.

And Zaypher, most fully synthetic and/or semi synthetics (mineral also) would be good enough for normal use, as long as they all exceed API SM grade.

I've used oil like Royal Purple, Amsoil, and now Petronas fully syns, I've also used cheaper mineral 20W-50 in my cars and again, they won't give you noticeable performance increase. But with good quality oil, you are rest assured when you trash your beloved car.

But I have this tendency to service earlier than the recommended interval. Mineral use for 3-4k km, semi syn 5k, fully syn 8-9k.

I have been reading that the Shell Helix Full Synthetic is a little heavy. But how's it compare to Castrol Semi-Syn? Is it right to say that any Full Synthetic will have a better viscousity than any Semi-Synthetic?

MOTUL 6100. very good. especially in high revving.
