    So what Oil is everyone using in there Alloytec's?

    Mine's due for a service soon, so I'm wondering what Oils would be best...

    Many choices, make sure you read the Owner's Handbook and check the Specifications area. Stick with what Holden recommend. Alloytecs do love good quality clean oil. Anything less is detrimental to their longevity.

    Im using Mobil Semi Syn 15w-40, no issues.

    I want to give Nulon 15w-40 a go, see how that performs.

    Brand matters very little imo. I would choose an oil based on viscosity (specified or very close to recommended), specification (product data sheet), and manufactures approvals. As for oil change interval I would say the price you pay is somewhat proportional to how many kms you travel and how long it stays in the sump.

    As for a filter, go with a genuine one. About $15, made in the USA.

    I use Nulon as well... has always been good for my car, no problems whatsoever. I get it at trade price through my dad, a service never costs very much for me at all. All parts at trade price but no labour costs, and I use one of my dad's hoists, and his tools.

    Anyone else had bad experiences with Magnatec 10W-40. I just bought some for my next oil change, i'm hoping its not as bad as mentioned above and that was a once off...

    I'd avoid Magnatech, an oil that "sticks" to parts? No thanks, no wonder the oil sensor got fubar. It's also a no-no for turbo's, i'd imagine an oil with some gummy sticky crap put through it.

    Just go a good quality organic 15-40 or something around there, no need to go full synthetic unless you have spare $$ to throw around. Doing an oil change regularly (every 7500kms) is better for the engine that any expensive oil. I changed my oil and filter on my turbo lancer every 5000kms because it was an easy DIY.


    Oh yeah always let your engine warm up and take it easy before bringing it above 3000rpm. 90% of engine wear is done within the first 10 mins of driving. If you really love your car you should let it idle after a cold start for a minute.

    I usually run the Magnatec and change to Edge for track/skid pan days because Im changing the oil just for that day anyway so I might as well chuck in something that supposidly helps, so 11 out of 12 months a year mines on Magnatec - no issues to date.

    Been running only Magnatec for 3 years, this year was the only one where Ive changed to Edge for the one off thrash days.

    The Magnatec sticking is a fact, nothing to do with it sticking and screwing up a sensor. Magnatec contained 10-20% Ester base Group 5, which has a natural polarity to metals, meaning it is attracted to it, almost like static paper to a plastic ruler. Mobil 1, Castrol Edge, also contain some of it as besides sticking, it has high load pressue capabilities and a natural solvent (cleaner) mixes well with the anti wear and other additives and seal sweller. The possible problem with Magnatec may lie in the other 80%, possible cheaper base oil and additives. Some engines love it like the LS1's. Sodium is the additive sometimes used to effect oil pressure.

    I have been told of some issues in Turbo's on a BM or Merc cannot remember, but that is because it was used incorrectly with another ester based additive, so the seals over swelled. You recommend an organic oil which is exactly what the remainder of the Magnatec is. But definately some oils suit certain cars better than others. The key with overhead cam designs is go with a lighter startup weight, as you need the oil up top quicker than with older engine designs.

    we use magnatec at work in cars, i personally dont like it, seems to sludge i.e like the motors are burning the oil making the dark brown build up, thats why i firmly believe the bonds to the surfaces of metal as the marketing idea of sludge haha,

    i personally use valvoline durablend 5w-30, runs great in it

    Fair enough if you like magnatech by all means keep using it. But it's been said over many forums for all types of cars, (as andyman said) it builds up a black sludge. To me that sounds like the additives in the oil that makes it "bond" as their description states. I'll personally be avoiding it :)
