re: Synth Oils

[roa123]

Hi guys,

I just got my car back from the mechanic, and he asked me why i decided to change my oil from valvoline XLD to castrol magnetic. I remarked that Valvoline XLD is not a synthetic oil. He had been using valvoline in my car and his reason for using valvoline was because it was better suited to older cars, hence the slightly thicker oil would be much better than the thinner oils as they are used for the newer cars.
I have to point out that i trust my mechanic, he is very good at his job, he did my rebuild and fixed up the 4g63 transplant which was botched up by a previous mechanic. If you look at my engine it's pristine and i've had no dramas with it.
He is also using valvoline in his starion(4g63) which he rebuilt 10 years ago and still tops up with the same oil.
I mentioned a few people here on this forum use castrol, and he said his always used valvoline and it has always worked for him which is why he has not changed. He then follows up saying, alot of the rally cars use the newer oils, but then again their engine's get rebuilt frequently.
Anyways i thought i'd share that with you guys as it was something very different to what i have read in the past from this and other forums. Sorry about the long post.
I highly recommend my mechanic if anyone is interested in getting there engine checked out pm me, his located in springvale.
cheers,
Ritch

hahaha what a load of shit... not saying this guy is a bad mechince, but no way u shoild be using thik oil in a GSR or any turbo charged cars... i was going to use thinker oil in mine cause it used to burn a fair bit, the guy;s the my mechanic told me never to do that! it weakens the life in ya motor bla bla bla... he told me heaps... 5W magnatec is good to use n so is other synthetic oil...

fair enuff... i guess whatever oil works for you... just also noticed that in the castrol handbook, it has gtx3/ magnatec for vr4 engine's, and i know gtx3 is a mineral oil... http://neptune.spacebears.com/cars/stories/oil-life.html, has 2 case studies of oils that were tested, anyways thought i found this topic interesting, and found it surprising to hear my mechanic using a non-synthetic oil on a turbo car for the last 10 years, without any worries... thnx for the opinion..

Was unde rth eimpression magnatec wasn't synthetic?? Well at leats not fully.

Yeah you get your die hard mineral 20/50 guys (whatever is recommended in the stock handbook because the engine was designed and constructed to run that type of oil ), and you get your semi-synthetic fans and your fully synthetic fans... all swear by their own personal preference :lol: I will run mineral oil in my new engine first to wear it in but after that I am still not 100%. I have always been a die hard Castrol fan and all my oils, fluids, grease even window washer concentrate have been Castrol for years 8) This tips the scales in favour of Castrol Edge synthetics which are an outstanding proven product. Check out their cool website sometime and you'll notice a couple of hypo 4G63's I'm sure you'll recognise http://www.castroledge.com.au/

i'm now running castrol edge 10w60 full synthetic in mine.

i ran the motul 10w40 turbolight for a bit, but thought what the hell may as well go full synthetic.

yeh i was running mobil 1 super syn for the last 12months an been changing it every 5000k its a great oil the car runs great on it but its does burn it as it is thin so i recently started using mobil synth s which is semi synthethic an semi the price but it also runs terrific on that maybe a lil better as its an old engine etc etc tolerances etc except one thing on a cold morning the kick over the tappets tick for an 3-5 secs which they never did with mobil ...but watever suits u i guess u shopuld just stick to it u cant really say that one notable brand (mobil)is absolutely superior to another notable brands (say Castrol) equivalent so stick to wat u know i guess

my mechanic also recommends valvoline oil!!

although im still using castrol gtx3 since thats what the previous owner had used in it, cant complain, just gets a bit darkish/black towards the end when its due for a service, but thats normal

i recently started using mobil synth s which is semi synthethic an semi the price but it also runs terrific

x2 Mobil Synth S FTW

 

[lefty]

just got car back from service, my mechanic put in Olion/Oleon (i think thats how u spell it?) 10-40w, apparently semi synthetic, and apparently better than the castrol. Anyone heard of olion or have a website i can check out? cheers
