I was wondering what engine oil you guys use in your RST's. I've got a S1, that I've not owned for long, in need of an oil change. Think its running about 190BHP.

Halfords recomend 0w - 40 oil
RS specialist says this is too thin and recomends fully synthetic 15w - 50
And Fords say this is far to thick get a 5w - 30 part synthetic

Any help would be appreciated.

Had mine set up at Motorsport Developments recently and asked Stu the same question. Mines running bout 180bhp and he said 10w-50 semi synthetic. Everyone will have their opinion on this though.

 

everyone will have they're own opinion on this subject and there has been loads of posts asking the same question!!!
i use mobil 1 fully synthetic and as far as i am aware it should allways be fully synthetic.
silkoline 10w60 is also a popular choice

 

Allway use fully synthetic i use 5/40 in mine i asked the guy to look in the book when i bought my oil and it said to use 5/40 but as above everyone has there own opinion but ive allways been told to use fully synthetic

 

I use castrol RS 0-40 but most people say the turbo will love it but the engine will hate it as its to thin

 

10/40 or 10/50

and regular oil changes

 

Fully synthetic, Mobil 1, Motul or Silkolene. Preferably x/50 rating.

 

Magnetec 10/40 in mine. Perfect for it.

 

Mikey. How do you know it's perfect for it ? Yours does'nt go anywhere mate ! lol

 

0-40 is too thin and will be no good for the engine a 10-50 or 15-50 will be much better. I always use Mobil1 Motorsport in both my RST's.

Oilman can explain it all in far better detail as he's a bit clued up as his name would suggest

 

Suppose that is a very good Point .

 

 

always used 10w/40 magnatec in both my rs never had no probs change oil and filter every 1000 to 1500 miles dont no if this to much but never had 1 blow so its all good

 

mobil 1 all the way
