What really is the best grade of oil for the machines we drive??

I read a very cool article about tests they made on all the main engine oils on the market right now. But I cannot remember which ones came out the best.
But I do remember all of the leading big marketing brands didnt make it even close to the top. It really made me think.

They showed test parts how much the parts had worn, they were really interesting results. I just cannot remember the best ones, but I do know that these brands were not as well known, at least in the marketing advertising traps.

Just trying to remember if it was in Street Machine mag this report?? does anyone remember?

Was interesting anyway to bad I cannot remember the brands....

There was a big write up in Issue 108 in Street Commodores. It tests 18 different types of oil..... This however is not just for Ls1 engines its all types so some of the grades won't suit...

Alot of people use Mobil1 10W-30

or I know a few people who use Magnatec...

I wouldn't use a 10w30 in your v8. too thin. Its too hard on the bearings and cam, I run a 10w/50 full synthetic and it is rad. better fuel econemy and stuf.

I use Redline in the Senator and it was the only thing i would use in my 2 door HQ that i had a few years ago......it's expensive but then so are the cars we drive!!!

this is a bit of a personal one, most oils are adequite, my personal preferance is for pennzoil. i like oil to be a little thicker, for added protection, 20w50. thats what we run in our monaro. the oil temps don't get anywhere high enough to warrant the use of a syn. our falcon xr8 production car uses 0w30 edge (castrol) because we are trying to get 10 10ths out of it. but you should see it at the end of the season... one of my sport sedan engines, we run a straight 50 (pennzoil) this 350 sb chev is a 12.5:1, 8500rpm monster, pull it down at the end of the season, and the bearings look brand new. Sure the heavier oils cost a bit of power, but its good insurance

and change the stuff every 5000k with a filter

the oil that had the best protection in the tests you guys are talking about was "i think" Royal Purple "i think" or somthing like that, it was a brand that i never had heard of. The top brand oils definatly wernt as good as what there hyped up to be

My suggestion on this one if anyone reading this is looking for advice, is don't guess. take the question to the experts such as your local "performance" workshop. NOT THE LOCAL GARAGE!

this is such a loose discussion as it depends on the purpose and what you want out of it, just as generation motorsport mentioned.

I have no doubt that this discussion could go on for months with everyone having there own opinion on which is better and to be honest..... most would actually be right.... because it suits there own purpose.

when looking for the right oil, go to a specialist, describe your set-up in detail, describe what you are looking for in your engine (performance / reliablility or a balance) and get their opinion.

The worst thing that can happen with this discussion is for one of us to tell you what we think is the best (because it works for us) and then someone goes out and gets it and it does the exact opposite to what they want.

Booking my car in with Sam's Performance today for its 70k service and apparently they use this oil. Going to put it in my gearbox too. Ive heard some pretty feedback about this oil.

I use Castrol Magnatec. My car is an everyday family car 90% of the time. I change the oil every 7,000-9,000km. I figured that by changing the oil more often (and the filter!) is more important than the type of oil - for my car's purpose.

People who put expensive Mobil 1 fully synthetic Oil in their family cars that potter along at an average of 1,800rpm 90% of the time are probably just brand name whores. Fair enough if you've got a cammed car that revs to 7,000+ rpm and it spends most of it's time there...

I did use synthetic oil in my previous turbo car - but that makes sense because of the higher oil temps and critical job of keeping turbo bearings lubricated at 100,000+ rpms.

So be careful what you ask for.....it will depend on what purpose your car is for and how diligent you maintain it, how you drive it, what temperature you tend to operate it in and whether it's city or highway driving etc are all variables that make a better decision than price.

:?:?:? I'm so confused now. Understand it all with the w/w but still no clearer as to best oil for my 09 LS3. And I didn't even ask...but now I don't know weather to start listening to Prince or stick treacle in my glove box. Thanks...I think?:p:lol::lol:

I used Magnatec in my VX which was rattly with Mobil. Worked a treat.
Now I use the recommended Mobil 1 synthetic in the GTS and buy it when its on special at Supercheap Autos. Costs me half what Holden sell it for that way. I honstly can say that it seems no better than the Magnatec and only use it because it is recommended and I'm in warranty still.

Yeah I'm currently using Magnatec aswell, totally eliminated the nasty piston slap sound on cold start ups, seems to work really well.
