I'm currently using mobile 1 motor oil in my car and heard of a few nasty stories about it.
Just wondering about the types of oils out there and if anyone has had good or bad experiences with certain oils...I don't want to be running my car with dodgy and expensive oil!
Full Version: Motor Oil
choosing oil you need to take a shitload into perspective like: how many km the engine has done, the temperature you run the car in, how long you run the car at any one time (IE drag cars) and more.
since you have to take all this into account the will never be one perfect oil for your car as all do differant things and cover differant ranges of things.
still it might help to check out www.valvoline.com.au they go into as much detail as possible (for a commercial site)
any way hope it helps if not come see me at indy's

I've always used Penrite Oil in all my cars. Never had a problem. Even with the nitrous fed stroker 6 in the Torrie the oil was always spotless when changed.
As far as oils go, i'd recommend Penrite to anyone.

i am with 1/4 mile on this one and its as good to back the only fully assie oil penrite 
As above ^^ always used it too
always sell and used MOTUL oils.
personal preference.
castrol edge is new but haven't heard much about it though.
some big HP car down south use it.

Im a Penrite fan.
Motul Oil for engine and box. I just changed my oil as most of you know and really notice a difference! So did my wallet, but some things you can't avoid.
i used mobil 1 never had a problem never heard anything bad about it, but i think i'm gonna go Pennrite next time if it's an all aussie oil
Penrite sounds pretty popular.
Can anyone explain in depth about the 5W-50 thing? Obviously different options are out there. That's just the Mobile1 that i'm using at the moment.

Mobil 1 is excellent, so is penrite it isn't bad. Motul is very good as well - especially their 300v series stuff.
The 5w-50 thing is the SAE rating i think. Someone correct me if im wrong but the first value is the SAE rating for the oil at low temperatures and the latter value is the SAE rating for the oil at higher temperatures.
Basically your oil is thin when cold and is thick when hot. ?
-EDIT-
Ok my explanation sucked.. Google is your friend -
Multigrade oils typically begin as base oils, such as 10W. Then viscosity-index modifiers (polymers) are added in an effort to stabilize the viscosity. This allows a 10W40 oil to flow like a 10W at cold temperatures and a 40W at higher temperatures.
The multigrade oils' viscosity modifiers are long-chain molecules that lessen the change of viscosity with temperature variance. In the past, the polymer additives (used to thicken the oil) were sometimes susceptible to viscosity loss. Permanent viscosity loss occurred when high shear forces (such as the relationship between the main bearings and the crankshaft) actually break the polymer molecules into less-effective smaller pieces. On a similar note, temporary viscosity loss also occurred when the polymer molecules aligned themselves in order to create a path of least resistance.
Fortunately, today's additive packages have improved oil's shear-resistance. However, oils with the same rating from different manufacturers can exhibit different viscosity ratings in an operating engine, depending on the shear stability of their viscosity-modifying additives.
For technoids, weights are defined thusly (stokes and centistrokes are measurements of viscosity):
"SAE 30 is SAE 30 no matter what the "W" prefix number is: 0W, 5W or 10W. This viscosity in centistokes (cSt) @ 100 degrees C is with the minimum of 9.3 cSt and a maximum of 12.5 cSt.
"SAE 40 is SAE 40 no matter what the "W" prefix number is: 5W, 10W, 15W or 20W. The viscosity @ 100 degrees C is within the minim of 12.5 cSt and a maximum of 16.3 cSt.
"SAE 50 is SAE 50 no matter what the "W" prefix number is: 5W, 10W, 15W or 25W. The viscosity @ 100 degrees C is within the minimum of 16.3 cSt and a maximum of 21.9 cSt.
"SAE 60 is SAE 60 no matter what the "W" prefix number is: 10W, 15W or 25W. The viscosity @ 100 degrees C is within the minimum of 21.9 cSt and a maximum of 26.1 cSt.
"There is no SAE 70 and no one is likely to make one with a "W" prefix number although it is possible using a synthetic base oil. This viscosity is identified as Grade 70. The viscosity @ 100 degrees C has a minimum of 26.1 cSt and no maximum."
The difference between a multigrade and a singlegrade oil: The singlegrade can't pass the low temperature viscosity test. If it did meet one of the following "W" viscosities, it would be a multigrade.
Singlegrade oils will become obsolete for performance engines in the future. We dropped SAE 30 and SAE 40 because SAE 10W40 does everything 30 or 40 can do—and some things the straight grades can't do—like increasing horsepower. If an off-roader doesn't like 10W40, then use 20W50. It can do everything a 10W40 can do except pass the sub-zero viscosity test at -20 degrees C.
Multigrade viscosities are run at six different sub-zero temperatures. When a racing-oil designer puts a formula together, he has to know the viscosity at 100 degrees C of every component in the additive composition. He has to have a target viscosity objective for the finished oil in each SAE grade. Once a formula is established, the technician who supervises the blending has to duplicate this formula in the correct proportions every time the product is blended. The viscosity at 100 degrees C has a plus or minus written into the oil's quality-control specification.

Penrite 10W 40... mmm rotar nutrients <3
Ohhhhh and Maaaalcolm.... Is that cluuuuth in yet... Pm me your number... I lost yours when i broke my phone... thaaaaanks yoooooou
We used mobil one for aaaaaaaaaaaaaaaaaaages in the bluebird......
Now B changed it to MOTUL and the vehicle runs smoother and quieter. It is actually awesome the diffference that it has made.

i'd say castrol and motul
depending on ur application, lots of factors...
