What brand of engine oil do people prefer and use?

I used Helix on my VS, sometimes valvoline, with my VT i have used both Valvoline and Castrol, stick with those 3 and you cant go wrong

 

I use Penrite LPG oil. Haven't had any problems with it. No engine deposits left yet. I hear the castrol brand is also good too.

 

Valvoline

Might try the Castrol Magna ???? something ....

 

Mobil 1 Synthetic for my LS1

 

used Shell Helix with about 30ml of molly bond for years, then couldn't get molly bond, so just tried helix and found after about 6 weeks engine sound and felt like ****. Now I use Castrol Magnatec, expensive but nice... apart from having magna in the name...lol

 

i use castrol magnetic car runs fine

 

I've always been a fan of Valvoline, in particular the VR1 Race Oil (formerly known as Durablend)

 

I use Castrol GTX2, changed every 5,000kms.

Thats what the car has had from day 1, so why change a good thing now :yeah:

 

Statesman V6 with 206,000km's gets treated to Shell brand oil every 5,000km's. I am unsure of the name. It aint Ultra or Helix. In a green shaded bottle. Semi synthetic with a weight of 15-50.
seems to work a treat.

 

french made oil called Motul, visco weight, 15W/50 semi synthetic!
works fantastic, run it in both the 5L SS n the 3.8 6!
although its just on $50 for 5L

 

I use Penrite LPG in both my 5.0Lt VR's ( Change oil/filter ever 10,000Km ) and never had any problems. The SS done 240,000Km's. Also used it in my old Torana with a hi reving six and never blew it up. Pulled down motor a few times for mods and found it to be clean.

 

I use Gulf Western such a nice oil also use it in our dragster never had a problem with it and is much better for the price than alot of imported oil. see www.gulfwestern.com.au

 

ive only ever used Penrite LPG oil,since my engine rebuild, never had a problem

 

I've used Castrol for over 25 years and can't complain. I currently use GTX3 in my 5 Litre. Half of the secret is to change the oil at least every 5,000 k's.

 

mobil 1 i think its fully synthetic or something.....

pretty much everything that goes threw holden.
dad works there and i know its expencive so same as the fuel it goes on his card and its free...

 

U Know what i mean

Valvoline XLD Plus 20w 5o and Valvoline Oil Filer

 

Use Castrol GTX2 20W/50 in my VS Berlina.

 

I been using mangatec for ages - apparently the "manga" is just lead and it ****s your motor right up (given enough time) - better off with the good stuff - Mobil 1 - this is a according to a professor in mechanical engineering - so you been warned.

 

Fully Synthetic for me!

I only use a fully synthetic oil, Mobil 1 in my case.

Performance of the fully synthetic oils is better than those based on mineral oil.

However, you might not want to use a synthetic for the following reasons:

1. You are not keeping the car long, and don't care if it wears out quicker.

2. You cannot afford the small premium of synthetic oil, and don't expect to keep the car a long time.

3. The car already uses a lot of oil, either through external leaks or down the valve guides. Oil usage will go up with a fully synthetic for these scenarios. On the other hand, it should use less oil if it is getting past the rings.

I buy mine at the periodic 15% sales at Kmart.
