ok im no oil expert but i usually use Millers in my 3 door.

anyway..... have just been into Halfords and see that theyre doing buy one get one free on 5 litres of fully synthetic oil.

The one i was interested in was their 5w/50 "Motorsport" Oil which they describe as being suitable for track days or "enthusiastic driving"!!

anyway its 31.99 for 10 litres at the moment at i was wondering if anyone had experience of this oil as if its any good then 31.99 for 10 litres is a bit of a bargain!!!

for info i want to put it in my 3 door running apoprox 310BHP.

Cheers,

Mark

 

Additional Information link dont work

 

It should do m8, I just clicked on it and it worked!!

 

Bargain, its probs made in same batch as Millers or summat anyway

 

i wasnt sure what 5w/50 meant?

I usually like a slightly thicker oil in the cossie.

the other one they have is their standard synthetic which is 5w/40

could someone tell me which of the two would be more suitable?

 

Wont open on my pc

 

5w50 is better than 5w40 for trackdays

 

I dont ever use the car on track but i do drive it "enthusiastically" sometimes!

 

What if your car says run on 5w30... Are you safe putting 5w50 in?

 

Hmm.. think i'll stick to Mobil 1 15w50 from Matt Lewis at £40 odd pounds for 10 litres.

Never seen a 5w recommended for a cossie by anyone !!!! Awaiting to be proven wrong

 

Dan NO
50 is to thick for modern Ford engines stick to 30. Otherwise you could have loads of problems, Ford found this when the Mondeo first came out with the Zetec and they used 40 oils. Later changing the recommendation to 30.

 

dont it say 15,50 not 5,50

 

yep the description does but it says 5w/50 on the bottle.

Found this:-

VISCOSITY

Most oils on the shelves today are "Multigrades", which simply means that the oil falls into 2 viscosity grades (i.e. 10w-40 etc)

Multigrades were first developed some 50 years ago to avoid the old routine of using a thinner oil in winter and a thicker oil in summer.

In a 10w-40 for example the 10w bit (W = winter, not weight or watt or anything else for that matter) simply means that the oil must have a certain maximum viscosity/flow at low temperature. The lower the "W" number the better the oils cold temperature/cold start performance.

The 40 in a 10w-40 simply means that the oil must fall within certain viscosity limits at 100 degC. This is a fixed limit and all oils that end in 40 must achieve these limits. Once again the lower the number the thinner the oil, a 30 oil is thinner than a 40 oil at 100 degC etc. Your handbook will specify whether a 30, 40 or 50 etc is required.


So the question still remains.......will 5w/50 be alright to run in my cossie!!

 

jUST TO SAY GROVE USED 5/50 IN MY rs500

 

and all seems ok?

 

that is generally correct, but this bit..

..is bollocks. a lower number means a lower viscosity at the lower test temperature - nothing more. whether a low or high viscosity is better for your engine is another thing

 

i just want to know if people would reccomend using 5w/50 in a cossie!!?

 

dont bother

i just ordered 10 litres of mobil 1 motorsport of matt lewis for £55 inc delivery

just PM on here

 

but this is £23 cheaper!!???

 

tHE COOSE IS YOURS what does you tunner say !!

 

if you want a simple answer, just buy silkolene pro s from oilman and be done with it
