From info on here and other places the oil for my 57 reg 2.2 TD4 HSE is 5w 30 which is what i used to top it up with. The car is due service soon so i looked through the paper work and on the last service the print out definitely states they used Mobil synthetic 5w 40,any ideas which is right guys ? Many thanks.

You are right using what you have in topping up.

It should meet Ford spec M2C913 B/C and be A5 5W-30

Manual says 5w-30. Probably just a type error on the printout.

Thanks for replies,the print out will be going with me when it is serviced and i will query it.

I've found another service reciept now again it says 5w 40 bit worrying.

not a great deal of difference, so nothing to worry about.

as long as it meets the spec mentioned in previous post.

5W40 is a thicker oil when hot, as said, probably wouldn't do any harm, but best make sure it is the recommended 5W30 added this time.

It's the first number, which is the cold viscosity which is the most important. The last thing anyone wants, is poor lubrication when starting up.

Well car went in for service last week and i was given a load of confusing guff about oil and numbers but don't worry was repeated a lot. £360 service and another £1000 plus VAT recomended work brakes and discs etc which i am getting done by a friend,the bit that made me laugh was rear wiper arm seized £66 plus VAT to fix,three squirts of WD 40 later its all better

Forgot to mention was told get the car there for 8:30 it will be first job,didn't get out until 11:35 they tried washing car even though a big do not wash sign was on the dash too.

They is a couple of threads on here regarding the rear wiper, you may want to search for them, basically you need to strip it down, clean the wiper gearbox out and regrease, burntout motor or worse if you don't  p****d off with a Digital Keyboard Warrior

Ive read the threads mine was the spring that had siezed yes they wanted nearly £80 to replace it.
