im wondering the best oil to use when running in my zetec turbo as ive heard several different opinions, should it be mineral, semi symphetic etc?

 

have u had a rebuild or just taking it easy........................after a build use a mineral oil that is recomended for the engine..(manufacturers hand book)...ie 10/40........10/50 etc

 

mineral all the way!
and dont take it too easy when running a car in,, you need pressure on the ring lands for them to force themselfs onto the chamber walls!

 

Cars all running then?

 

It does make me laugh when people often say 'use the cheapest crap-iest oil you can find.'

 

After Karl built my engine, I used mineral for about 1000, then semi for about 1000, and now just put Mobil 1 15/50 in it.

As said, dont be too shy on the loud pedal either, but that doesnt mean redlining it either

 

ive been speaking with ian howell and he's recommended me on how to run it in, im hoping if all bits arrive and all goes well and i get the other car out the garage and mine in i can have it in wednesday and running by friday (with no xhaust) lol, im going to make the engine loom up and leave it long the re-do it when all the extras are on the management and running so nothing is missed , going to try for central day now, absolutely gutted i wont be able to show it though, anyone pulling out who has a ticket for sale?

 

the only person you should see about running-in is your engine builder he will tell you what you should be doing,
i use millers running-in oil, yes they do a specialised oil for that very job... i will do 400 miles ish and cycle between 3K and 4K alot and also not be to gentle with it... try and get to allsorts of loads, up hills ..over run ect.. thats how i do it and never had an issue whatsoever.
good luck.

 

cheers guys, hopefully with the engine loom etc in she'll start
