Im about to change the engine and gear box oil, anyone any suggestions as to a top notch replacement for use in my Bravo HGT ?

Oils...

Hi Neil;

As U didn't mention your HGTs Km. I can not say much but, I can advice some in general as a proud owner of a HGT.

Engine; The use of fully synthetic oils improve the protection & engine performance. U can use lots of oils in the recommended range which is 10W-40. Don't use the thinner oils like xW-30, cause they're very thin that can penetrate the combustion chamber unfortunately. Keep the viscosity which is recommended.
I prefer Shell Helix Ultra 5W-40 Fully synthetic !
( In general the first number before the "W" means Winter performance; which must be low, and the last number with two digits means the viscosity. The lower numbers means the thinner oil film between surfaces.)

Transmission; I tried lots of additives & oils brands with lots of failure. Finally I got the best transmission oil by experiencing;
Castrol SAF-XO 75W-90 !!! U can't believe the result.

Hope those stuff helps.

See ya !

Gear Box Oil Change

Im at 44k but as I have just purchased the car I was thinking it would be wise to change it.

Change Them All..

Definitely change the oils with proper & improved ones.
P.S: Don't forget to use a quality oil filter.

P.S 2: U can also change the radiator liquid, 2/3 Anti-Frezee + 1/3 Diluted water will be fine !
Also change the brake fluid with a DOT 4 one.

Where do I get Castrol SAF-XO-75VV-90

Cannot find it localy, Fife.
Please help.

Castrol

Hi,

Check the Castrol web site for a dealer near u or contact to the nearest authorised BMW( Sorry..) service.

Hope this helps.
