what's the verdict on Castrol R? is it true "synthetic" ?
I'm only asking 'cos Supercheap Auto seems to always run out of Mobil1 when their 25% sale time rolls around... (which makes me super-cheap too !)
synthetic oil - Castrol R ?

Hmmm I always thought that asking about motor preference is like asking for beer preference everyone's different...
Have heard some good and some not so good stories from mechanics as to Castrol, some say it will causing glazing others have said that they are the be all end all...
I have just changed my oil from Penzoil Semi-Syn 10W-30 to Mobil Super S Semi-Syn 15W-30 so far with the Mobil, I'm noticing less oil usage which has to be good and it wasn't bad for $40 at Repco
and still using my Fram filter

im running the shell fully synthetic (10/40 i think)...the only reason i switched to fully syth was because of the turbo, otherwise id stay with mineral or semi synth,
the shell fully synth seems ok.... lifters dont tick..engine hasnt blown up.......must be ok!

I would agree re oil preference....I have been a Castrol user (incl full synthetic)for many yrs in both road and competition cars.
I believe that 'quality' oil of the right viscosity, changed regularly is more important than actual brand.
In my tweaked naturally aspirated 1.8 I am using Castrol Magnatec on 5000k oil changes. I get some initial occasional lifter ticking as the oil approaches its 5000klife.
When I bought my car, the oil was black and hot pressure fluctuated with a lower than expected reading. From its very first oil change, pressure improved markedly and has never budged in the last 25,000k.

Looks like some are, some are blended, and some are mineral. It depends on the viscocity. The 10W-60 and 0W-40 seem to be the only fully synthetic grades.
