Need some oil for my freshly built cvh . Which is best for the initial start up and running in ?

Thanks in advance

nigel b

I used castrol gtx in mine for running in

Rollinz

Are you serious! ??

Never use fully synth for running in!


You only get 1 chance to break an engine in!
Mineral oil or propper running in oil

Start car.. Let it tick over 2-3 mins then give it some,

Cheap shit mineral oil mate, think its normally 20w 50 or something

nigel b

its semi
my engine with its rings had to be run in hard

Rollinz

Which is why you dont want good oil for running in,
You only get 1 chance at it, and doing it right determines if it will be a good en or not,

Millers do a running in oil for Ł15 5ltrs

Start it, and use it! Make the engine work how its going to work the rest of its life!

Mine was doing 1.6 bar within an hour of been started

Millers it is then

I was told to start it run it for 5 mins . Turn it off change the oil then run it for 500 off boost fand then change the oil again and then do another 500 miles again off boost to run it in properly . Some people agree and some dont ............

Run them in hard is how ive always done them,

As i said you only get 1 chance to break and engine in.



If it blows up... It wasnt built right!

I like the logic behind that but dont think i have the bollocks to do it

Rollinz

I know what you mean mate as it goes against what you think is right...


But the rings and bore have got to take to each other to get the best performance from the engine,
If you pu55y about for too long they wont take 100% and your new engine will either use oil or never pull has hard as it "could" or both of those things...

The "only" danger that should arise is the rings could break if you havnt done the ring gaps correctly...
But this goes back to what i said too.... If it goes wrong... It wasnt built right

Don't forget to add a ZDDP additive to your break in oil.
This will greatly help camshaft/lifter break in.

The zink additives have been all but removed in engine oils. For old engines that use flat tappets the ZDDP additive is a must.

Thanks for the advice i'll be sire to get some of that

Now another question , my engine builder told me to start the engine run it for 5 minutes then drop the oil . Now would you use millers running in oil for the initial start up and then drop it and replace it with millers running in oil ?

Theres 2 types listed and then a classic

Is this the right stuff

Rollinz

If you want to do it the way your engine builder says then yes just keep using the miller running in oil,

Altho there is no real reason to drop oil so soon afterwards... The oil filter stops debris...

Its a strange one this , this is the first engine ive had built and its cost thousands with the management aswell so want it done right . You get told one thing off the guy that built the engine so you aotomatically think thats gospel . And then others like yourself who have run new engines in before say different

I think im going to do it like he advices so if anything goes wrong atleast i know ive done what he recommended .

Thanks for your help though fella its appreciated

At least following his advice if somthing did go wrong then he should warrent the engine,
