yea yea after tested, post the result here ya.... :)
still waiting for the oil, dunno when reach my workshop....
still waiting for the oil, dunno when reach my workshop....
one of my friend had tried this torco oil and he his claimed, engine very light and smooth... his on Vtec la, not turbo.
that's why pull my attention to find out how good can this be.
i never use amoil before, not sure hows the qaulity... post your review as well~ hehe

sure i will:_:
hmm... sounds like the quality very good also, next time i also wanna have a try with this tarco engine oil la hehehe...
btw how much is it?
Amoil is selling RM83

RM240 for 4 litres is expensive to pay for 10/30. Because mainly over RM200 we could buy 10-15/60. Which has more better operating range for cars.
From their site, i see that they cater more to motorcycle oils than cars. Explains why they like thin oils. BTW i wonder why the put up them winning car shows and bike shows when they should be hitting the racetracks. Crazy marketing technique.

ops... bro... i have a correction...
the lub's i bought its actually 5w-40... not 10w-30.
the price are different from thise two. truely apologized...

will be testing on 3S-GTE another 2 weeks time. boguht it in store room now, waiting for the best time to perform test.
hm.. i'm not pretty sure what that series of lub's my friend's v-tec are using, will ask for the detail.
by the way, what's the price range for 5w-40?

don't you think 5w-40 the viscosity too thick ?
unless your engine have lost a lot of tolerance n piston ring almost torn out already...
plus your FC might be lower due to thickness of the oil...

sache
5W-40 representthe viscosity grade, it also tells you the thickness or the oil...
The first number indicates the viscosity of the oil at a cold temperature, while the second number indicates the viscosity at operating temperature
The higher the number the thicker the oil, vice versa...

ooOOO for Turbo, i thought it was for n/a engine...

well, the one i bought its 5W-40 and i'm not to sure what's the grade of lub's my friend bought for his v-tec. i believed it's not 5W-40. it's not compatible and suitable for his v-tec.
hehe.. sorry to confused you guys...
cheers
hehe.. sorry to confused you guys...
cheers
no problemo...
try to search in other forum...or else...
since that malaysia is not suitable with 5W...cuz of the "winter" too low...no saying can't use...5W normally used in cooler climate country...
please refer to this graph...

Motor Oil Primer
by Ed Hackett
[Ed is a chemical engineer who works for the University of Nevada's Desert Research facility -- Ed.].
Choosing the best motor oil is a topic that comes up frequently in discussions between motoheads, whether they are talking about motorcycles or cars. The following article is intended to help you make a choice based on more than the advertising hype.
Oil companies provide data on their oils most often referred to as "typical inspection data". This is an average of the actual physical and a few common chemical properties of their oils. This information is available to the public through their distributors or by writing or calling the company directly. I have compiled a list of the most popular, premium oils so that a ready comparison can be made. If your favorite oil is not on the list get the data from the distributor and use what I have as a data base.
This article is going to look at six of the most important properties of a motor oil readily available to the public: viscosity, viscosity index (VI), flash point, pour point, % sulfated ash, and % zinc.
Viscosity is a measure of the "flowability" of an oil. More specifically, it is the property of an oil to develop and maintain a certain amount of shearing stress dependent on flow, and then to offer continued resistance to flow. Thicker oils generally have a higher viscosity, and thinner oils a lower viscosity. This is the most important property for an engine. An oil with too low a viscosity can shear and lose film strength at high temperatures. An oil with too high a viscosity may not pump to the proper parts at low temperatures and the film may tear at high rpm.
The weights given on oils are arbitrary numbers assigned by the S.A.E. (Society of Automotive Engineers). These numbers correspond to "real" viscosity, as measured by several accepted techniques. These measurements are taken at specific temperatures. Oils that fall into a certain range are designated 5, 10, 20, 30, 40, 50 by the S.A.E. The W means the oil meets specifications for viscosity at 0 F and is therefore suitable for Winter use.
The following chart shows the relationship of "real" viscosity to their S.A.E. assigned numbers. The relationship of gear oils to engine oils is also shown.
Multi viscosity oils work like this: Polymers are added to a light base (5W, 10W, 20W), which prevent the oil from thinning as much as it warms up. At cold temperatures the polymers are coiled up and allow the oil to flow as their low numbers indicate. As the oil warms up the polymers begin to unwind into long chains that prevent the oil from thinning as much as it normally would. The result is that at 100 degrees C the oil has thinned only as much as the higher viscosity number indicates. Another way of looking at multi-vis oils is to think of a 20W-50 as a 20 weight oil that will not thin more than a 50 weight would when hot.
Multi viscosity oils are one of the great improvements in oils, but they should be chosen wisely. Always use a multi grade with the narrowest span of viscosity that is appropriate for the temperatures you are going to encounter. In the winter base your decision on the lowest temperature you will encounter, in the summer, the highest temperature you expect. The polymers can shear and burn forming deposits that can cause ring sticking and other problems. 10W-40 and 5W-30 require a lot of polymers (synthetics excluded) to achieve that range. This has caused problems in diesel engines, but fewer polymers are better for all engines. The wide viscosity range oils, in general, are more prone to viscosity and thermal breakdown due to the high polymer content. It is the oil that lubricates, not the additives. Oils that can do their job with the fewest additives are the best.
Very few manufactures recommend 10W-40 any more, and some threaten to void warranties if it is used. It was not included in this article for that reason. 20W-50 is the same 30 point spread, but because it starts with a heavier base it requires less viscosity index improvers (polymers) to do the job. AMSOIL can formulate their 10W-30 and 15W-40 with no viscosity index improvers but uses some in the 10W-40 and 5W-30. Mobil 1 uses no viscosity improvers in their 5W-30, and I assume the new 10W-30. Follow your manufacturer's recommendations as to which weights are appropriate for your vehicle.
Viscosity Index is an empirical number indicating the rate of change in viscosity of an oil within a given temperature range. Higher numbers indicate a low change, lower numbers indicate a relatively large change. The higher the number the better. This is one major property of an oil that keeps your bearings happy. These numbers can only be compared within a viscosity range. It is not an indication of how well the oil resists thermal breakdown.
Flash point is the temperature at which an oil gives off vapors that can be ignited with a flame held over the oil. The lower the flash point the greater tendency for the oil to suffer vaporization loss at high temperatures and to burn off on hot cylinder walls and pistons. The flash point can be an indicator of the quality of the base stock used. The higher the flash point the better. 400 F is the minimum to prevent possible high consumption. Flash point is in degrees F.
Pour point is 5 degrees F above the point at which a chilled oil shows no movement at the surface for 5 seconds when inclined. This measurement is especially important for oils used in the winter. A borderline pumping temperature is given by some manufacturers. This is the temperature at which the oil will pump and maintain adequate oil pressure. This was not given by a lot of the manufacturers, but seems to be about 20 degrees F above the pour point. The lower the pour point the better. Pour point is in degrees F.
% sulfated ash is how much solid material is left when the oil burns. A high ash content will tend to form more sludge and deposits in the engine. Low ash content also seems to promote long valve life. Look for oils with a low ash content.
% zinc is the amount of zinc used as an extreme pressure, anti-wear additive. The zinc is only used when there is actual metal to metal contact in the engine. Hopefully the oil will do its job and this will rarely occur, but if it does, the zinc compounds react with the metal to prevent scuffing and wear. A level of .11% is enough to protect an automobile engine for the extended oil drain interval, under normal use. Those of you with high revving, air cooled motorcycles or turbo charged cars or bikes might want to look at the oils with the higher zinc content. More doesn't give you better protection, it gives you longer protection if the rate of metal to metal contact is abnormally high. High zinc content can lead to deposit formation and plug fouling.
