Search first, ask questions later

Plenty of threads on this subject.

Blackbeastie is correct but shell ultra helix for my chariot!!

Kind of rather depends what car you have!

Turbo = 5w40 Fully Synth

Non Turbo = 10w40 Semi Synth

IMO.

I favour castrol 10-40 magnatec and change it every 5k , I do a fair few cold starts in winter and like the protection.

much appreciated all the useful replies, i am running 10 40 semi which is making my engine tap at 2-3000 rpm. its a t5r with 101k on the clock and I was asking a simple question as I have had 15 different answers so far from garages and dealers alike. I was under the impression thats what this forum was for and I have already done the searches as with tapping, rattling ect. again the useful replies are much appreciated.
regards

is 5-40 thinner than 10-40? I am trying to work out if its too thick and not reaching some oil ways or too thin and not working as it should.

I think because these engines have hydraulic tappets, go for the fully synth 5w/40 as it is important to keep the gap right on the tappets AND you have a very hot turbo whizzing around at the end of it, so you need a good quality fully synthetic. I use Valvoline where possible, or shell helix ultra 5w/40, change every 4-5k miles (7-8k km on my car!). Ask VT about this or do a search for 'OILMAN' as he did a good response on this subject!
