personally i think Petro Canada 5W/30 being reasonably price for less than RM 100/4 liter.

Personally I will go for 10w/30.. If there is no oil consumption associated issue..

Go for it ...sure no regret..

Base oil and additive is a chemistry... Just like nasi lemak, you need good rice and nice sambal..

you got the point.. But even for the case of mineral, I prefer group 2 and above base oil.. I had been to a few lube blending plant, some oil I will avoid using.. Just like the case of nasi lemak.. Good ingredient but lousy cook..

I think we are in the same frequency , caltex delo 400 15w/40 API CI-4/SL, come with chevron hydro isomerise base oil. Isosyn = iso synthetic. This oil come with good viscosity index, some moly and adequate TBN no. I buy 200 liter drum. But at caltex station, 5 liter pack cost quite alot. Cheers.

I use delo 400 in my camry now..

you know i got so much oil.. need to try out right...

i like this statement..

This is not a coating process, is quite similar to grit blasting..

I always use this info when choosing my engine oil. There are more than these in oil technical datasheet and it means alot for those who understand ..

if zinc is the main ingredient, i can get you a FS motor oil with more than 2000 ppm and still cheaper than Torco and still API certified and approved oil

Bro, please check with Torco , API & ILSAC controls zinc on which viscosity grade of oil...you will have the answer

Added on August 6, 2012, 12:10 pm from the chart, i notice you are comparing SAE xxW-40 oil..for towing and modified engine and extra drain interval, go for higher HTHS value .. For fuel economy go for lower viscosity no at 100 degC.

Torco just tell you half of the story.. Otherwise how to sell their products at that price

Of course you cannot find ..because i cannot find in here either in http://www.torcousa.com/products-auto-pro.html

You are not missing the story, they are actually hiding the story..

The reduction of Phosphorus (primary source of Zinc or ZDDP aka ZDP) begin with introduction of ILSAC GF-2 spec.

ILSAC GF-2 set Phosphorus limit of 1%by weight max (1000 ppm) for engine oil.By 2004 ILSAC GF-4 spec, Phosphorus levels were reduced to 600ppm (min) and 800 ppm (max).These restriction and limits can be futher confirm in the API's "1509 Engine Oil Licensing and Certification System 15th Edition , April 2002 Technical Bulletin 3 August 19,2004 " & in page 2 of of the API " Form BGF4SM Engine Oil Licensing and Certification(EOLCS) Application for Licensure Part B-Product Data Sheet".

Phosphorus limits of 800 ppm apply to API SM SAE 0W20, 0W30,5W20,5W30 and 10W30 oils only..IF CF-4,CG-4, CH-4 or CI-4 categories precede SM or SL and or there is no API certification mark, the limit for phosphorus does not apply.

i am using this "CI-4 categories precede SM or SL"

are we comparing to this oil http://www.lucasoil.com/images/medialibrar...40_MotorOil.pdf

http://www.redlineoil.com/product.aspx?pid=5&pcid=21

redline seems like the best in the pool.. maybe shall give a try on my own if price is within my budget

any oil with below 220 deg C flash point is a no no for me

if you notice in torco http://www.torcousa.com/technology/TDS_SR-1%20MotorOil.pdf and http://www.lucasoil.com/images/medialibrar...40_MotorOil.pdf

with ACEA category of A3/B3 and API SM/CF which mean suitable for diesel engine oil, why not vice versa?

Just for reference.. No heart feeling

Added on August 7, 2012, 12:44 pmif this model is correct the figure for flash point is also wrong.. 410 deg F = 210 deg C
