Had my car in for service yesterday and therefore had the opportunity to change from the standard 10W 40 semi-synthetic oil that the dealer uses, to one of my preference.

After some debate / reading through the thread on the subject of oil posted by 'oilmansi', i decided to purchase some Silkoline Pro S 5W 40 Fully synthetic.

With the new oil being 5W instead if the 10W, hence been thinner, I seem to think that the engine noise seems more 'tappety' - when you think about it, it makes sense - just wondered if anyone else has experienced this, or if it me just listening for it more!.

Cheers

when i purchased my S2K( 3 weeks ago) I noticed that she was slightly "tappety" when starting up in the mornings. Upon inspection of the service receipts I noticed that 0W 30 had been used in the last 2 previous services (both main dealer). I have never seen anything that advises the use of such thin oil in an S2K, so when I had it service'd last week they replaced it with 10w 40 and now it is much better.

If its 5W 40 (which I use) then its going to be better with the coming winter months. It will flow slightly more readily in cold conditions, and yes, it may be a little noisier as the film is not as thick.

Note, they are the same viscosity at operating temp so you shouldnt notice the difference.

Mine is the same. I serviced in Sept & kept to Mineral (only had 4.5K miles) as soon as I get to 7k going to change to Mobil 1

When you say tappety are you sure you are not hearing the injectors?
I have just put Castrol fully synth 5W40 in mine and noticed no difference!

More than likely!, I think my ears are more susceptible to the noise because I'm paying more attention to every sound in the car, as I always do just after servicing!!

hazdjc - read through the link at the top, as oilmansi also sells the mobil 1 alongside a few others, and tends to suggest that the Motul and Silkolene perform better, but it's your choice! - either way he may be able to supply it cheaper than the dealers and save you a few quid!

I ordered my oil 3pm on thursday ant it was delivered 10am friday!.

Thanks for the responses!!

Open the bonnet & put your ear to them!

I thought my timing chain was getting noisy, but the squirters were having a loud day.

Actually, it's probably more that the engine is very quiet.

Aluminium lumps tend to sound a bit 'tinny' anyway.
