I was told to use castrol gtx coz its made for older cars and is thicker-therefore is less likely to leak out?? I could have been led up the garden path tho

20W/50 is 20W/50...
GTX is OK for running around, but I found it loses its viscosity too easy when thrashed... as we do.
Works well in the MiniMatics though.

Repco or Autobahn have it, or try the Castrol place in Scott Street, has a new name now, Castrol Edge, you want the 25W/50.

Black S, yeah yeah, between the Moke, the #@%$ing rain and Slycoon Larry, done very little. Still haven't unpacked the shed post Larry, then I have to get the generator fixed etc etc, you know what it's like. . .

If you read carefully on the Castrol website (as you do) and look closely at the product spec PDF's for both Formula R 25W50 and Edge 25W50 the only discernable difference is that they say Edge has "detergeant additives":



Where Formula R did not document any such additives.

Also worthy of note:





Here she is, have a look for yourself: http://www.castrol.com/liveassets/bp_in ... 969_05.pdf

It seems that they have taken away Formula R pdf for good. I know where there is a few bottles left, I better go get them!

Well I had HPR30 in mine when the gearbox went! Not saying it was the oil, but every other oil change that i've had the car, i've used Formula R, and every one since the box rebuild, Formula R!

atm i'm using Redline synthetic 20w-50. not exactly value-for-money at $35/Litre, but it seems to give more power (could be my imagination ) just had to try it but may not use it again - just gonna keep it in till after the dyno day and drags then might try some of this castrol stuff... should put it back on the dyno after that to see if theres any difference...

I gotta stick to the Penrite HPR40, been running it for over ten years on the same engine no problems with the oil, only the operator

Chong,
Both the old Formula R and the Edge whatever 25W/50 are SG rated, that really determines the detergent levels etc.
Beware marketing bumpf... (hey you should know that, being in market research! )

I've only ever used pretty standard oil in my car but Im told I need a racing type oil now getting more on tuesday...wonder if it makes a difference or not....

I really don't believe any of the negative comments I hear about synthetic oil. Welll maybe except one made by the head of Australia's military POL lab when I asked him what was wrong with synthetics..his answer "its too bloody expensive".

Luckilly Minis have a built in wear meter if you want to do some testing. Its on the end of the sump plug. Try this simple test. Run your Mini on any of the recommended convential oils for say 5000 kays. Empty the oil and check the plume of scarf on the magnet. Refill with a synthetic (I use Slhell Helix 15W60) and forget about it for around 10K. Now check the plug.

If you get uncomfortable check the oil pressure gauge. After a few thousand miles the pressure will drop off a bit when things get hot and bothered. You just won't see this with a synthetic.

Many people swear that synthetics aren't suitable for Minis because of the gearbox but this is precisely why its actually better. Check out what the numbers actually mean and you'll realise why.

Cheers, Ian
