i bought some motorsport 5w/50 for my s2, and since using it i've ended up with a oil leak? could the viscosity be too thin?

never leaked before i changed oil.

 

wont cause an oil leak, you have other problems.

check sump nut and filter.

 

is 15/50 not the recommended oil for an rst
anyway wheres the oil leak from? sump gasket?
i had a [prob with my engine breathers and had an oil leak from the sump gasket because of the presure,looks for the easiest route out,now the breathers sorted its stopped

 

no its coming from the turbo somewhere on the underside.

 

its ur braided oil return pipe try that

ford suggest 10/40 full synthetic oil

ive used 15/40 and it killed a turbo!

 

check the oil return hose to the block

 

so what is the correct oil to use?

i hear alot of people use mobile 1 15w/50

 

when the s2 was new from fords the oil was 5/50 but now times more on its 15/50 mobie one

 

It all depend's on how tuned your car is and what you use it for e.g track day's or just everyday driving i put 5/40 full synthetic in mine and the oilman said that would be fine as it's standard and i only use it for everyday driving no track day's or anything. If you want to know what oil to use give him a PM with the spec and what you use your car for and he'll tell you what will be best

 

i lookin on the chart i ford parts dealers and its reccomends 10/40 full sin for the ERST,

thats what i use, ask a few tuners what they would put in, think 15/50 is the wrong weight

 

Yeah that's when they were new like i say it all depends on what you use the car for as to what oil you should put in

 

yer just use part sin then gotta get the right weight

 

so is oilman the bloke to ask? im not running massive power, 200bhp max and its used everyday.

 

get a 2nd opinion im using 10w/40 im Running about 180 break and its off the road but i would use it everyday

 

Yeah give him PM and he will tell you what's the best grade to use and he can supply it for you too

 

sweet i'll give him a buzz, is his user ID just oilman? i'll search him in members listings
