I am now trying PENNZOIL SAE 30 straight weight made in USA, bought from ACE hardware, and its really good. Its a group II mineral oil, very good reviews on BITOG.

No, its only API SN, but i believe you dont need ACEA A3/B4. ACEA A3/B4 is basically setting HTHS min as 3.5, and TBN of 10 and above.It has a HTHS of 3.55 which is very good, and as you said no VII. The fuel economy does take a bit of a hit, but if it protects my engine better, why not ? i estimate the TBN is somewhere around 8 (based on other PYB)which is good enough for 10000km run. Besides, the higher the TBN, the lower the lubricity.
Already run 3000km with it so far and now only starting to darken. I will send UOA sample when the time comes. There are older stocks in ACE hardware with the black label of this oil, which is API SJ i think, that means prolly has higher zinc and phosphorous. You only need 3 1/2 bottles.
Now getting about 450km per tank of RON 95 with mixed 50/50 city highway driving. I also find this oil cools the engine very well, as seen by my oil temp and pressure gauges.

Zeng, that was discussed on BITOG about the TBN. I will try to find the link for you.
The FE is compared against shell helix ultra, i can easily get 500km per tank or close to it with SHU 5W-40, so i suspect most of the higher fuel consumption on SAE30 is from startup viscosity. lets continue talking on the other thread as Quaza suggested.

Not so bad at all actually. Try the SAE30 next time.

You wont go wrong with PETRONAS oil, especially semi synthetic and onwards. Dapat free, pakai jer . If its Platinum oil, HARDEX, MAZ LUB, Jetron then i'd be worried.

Hi delsoo. If you have read the links zeng posted, you would see petronas oil is well respected worldwide. You must understand Petronas isnt a 2 bit local company. They partner with world class blenders and hire some of the worlds best engineers..etc.
The only malaysian companies that i have no confidence in are..mazlub, jtx,hardex,platinum oil..jetron..you know what i mean..

how about hyrax ? , its good you haven't heard of them.

For a company like hyrax to claim that they make such good oils...they must really know their stuff right ? How is it possible on their top of the line 0w30 to have both ilsac gf5 and acea a3/b4 ? Either they dont know much about oils..mislabel..or downright lying.
So if they are cheating about these specs..what else are they cheating on ? API cert is one thing..but what if yr engine requires other cert ..and they claim it meets those specs but does not actually meet or exceed those specs..then how ?

So it is GF-5, that means cant be ACEA A3/B4. then they shouldn't display that on the label. API specs are pretty easy to pass.

I have tried BHP Syngard, nothing much to say about it, did not do a UOA, and i will probably not try it again and and have no incentive to do so.
BOSCH, Bardahl should be good oils, again , never tried them. Lexus , I dont know. Mitsubishi i heard is packaged by ENEOS and the full syn can be had for RM99 on sale at AEON. seems like a good buy , but the shear stability might not be up to par with Shell. Its a 5W-40, so if the shear stability isnt good might go down to a 30. Only way to know is do a UOA. May try it in the future but as I have already tried CASTROL 0W-40 and Shell 5W-40 and results are almost the same so I see no point in trying a other brand 5W-40, its probably not gonna do any better.
I am trying a 30 monograde now, just to study the effects of oil with VII and one without.
