Any one intersted in a doco explaining what all the numbers and letter are on the bottle and how they realate to the properties of the oil???

i know 3 seconds on google will answer it. but it seem alot of people dont know. and there also seam to be alot of people that think they know what it means but dont |

You might want to add suggested oils for engine, auto/man 6/8 gearbox and diff, since they do come up from time to time in threads, this can be a cut and paste from them. Might add how to select limited slip from std diff oils, etc.
Again this can be gotten from owners manuals etc, but I still see people claiming not to use Dexron in I6 T5's, for example. Maybe also a quick rundown how to change engine, g/box and diff oil.

they refer to the viscosity of the oil.
which is resistance to pouring the lower the number the easier it is to pour ie is thinner! eg 20w/50 has a viscosity of 20 when hot and 50 cold so when hot it runs easier than when cold..

You might aswell as it'll be handy for people to know about the viscosity. Also explain grade qualities - i.e. SG vs. SL.

Yeah, good idea for a doco I say.
Most people know basically the viscosity thing, but to go into more detail would be nice. I know I'd like to learn a bit more from a known source.

As stated, the information is readily available on google. However - all of this information is just background and definitions. I think what a lot of members would like to see is information that will help them select an oil. ie. once they understand the various measures - what should they consider when selecting a type/viscosity...

Isnt it 20 when cold, for easier start up flow, and 50 hot?

I'm inclined to agree with the idea of the docco all I know is that cheep oil is s**t and that you have to pay for quality but dont understand all the info on the bottle.

i'm working on it guys.
seems people want a bit more info then i was goin to put in, but thats fine. i'll search back through the forum and make a list of what people are using as well as the recomended oils, also i a liitle extra info that most of us will find very supriesing |

Viscosity
The purpose of the viscosity rating is to assure that, in the climate in which the engine is operated, the oil will always be able to flow through the engine's lubrication system. Eleven grades are defined. Six of them end in the letter “W,†beginning with “0W†and proceeding in steps of 5 to “25W.†The W stands for winter. The remaining five grades go from “20†to “60†in steps of 10, without the W. In general, higher numbers mean higher viscosities. The viscosity of the oil is tested at 100°C. Its viscosity must be greater than a minimum that is specified for each grade. For the grades without a W, a maximum viscosity is also specified. This test basically ensures the oil will perform in a warm, running engine. For grades ending in W, in addition to the minimum viscosity at 100°C test, a low temperature test is required. The temperature depends on the grade; for the 0W grade it is 35°C , for example. The purpose of the low temperature test is to ensure that if the oil's viscosity is low enough to permit cranking, it will also be low enough to be pumped through the engine. (Those processes involve different kinds of viscosity, so the cranking viscosity is measured in centipoises and the pumpability viscosity in centistokes.) The test temperatures rise by 5°C for each grade; oils with the lower numbers are intended for climates with colder winters. However, to select a viscosity grade for a particular car, consult the owner's manual and not just an outdoor thermometer. Multiviscosity oils, such as “20W–50,†must satisfy both the low temperature cranking and pumping test for the grade indicated first, and the 100°C test for the second grade. Such an oil would also pass the tests for all the grades in between.
