Need a bit of advice on running in an Engine on a 190E Cosworth

Hi guys,

I have recently had my entire engine overhauled...so new everything from pistons to valves, timing chain etc etc...so complete top and bottom end...

The comapny that rebuilt it put 15 w 40 oil in it. I have to change this after 500 miles...so my question is should i stick to 15 w 40? Im thinking of using the exact same oil and brand forever. was thinking about Castrol GTX magnatec 15w 40.

Are there any other things that i need to know about running it in?

many thanks!

What part of the country (world) do you live?

IN most cases 15W-40 is too heavy.

OF course avoid full throttle & vary the engine speed as much as possible.

I wouldn't use full throttle for the first 2000 miles. Try to avoid just straight highway droning @ a constant RPM. Changes in 500 mile intervals up to 2K IMHO isn't a bad idea either.

As for what weight it would be helpful to know where you live as mentioned above.

Hi guys, thanks for the useful responses...

Im in London, UK...

I was advised by the engine rebuilders to change the oil after 500 miles then normal servicing...I change it usually every 3,000 miles...
They told me after 1,000 miles i could drive it hard...but i think i like the idea of the 2,000 mile mark instead...what are the advantages of doing this?

but i think your advice is correct...maybe change the oil every 500 miles up to 2000 miles...

Is 15w 40 to heavey then? What brand and viscosity should i be using then?

thanks...


Zak

Well, in the summer months I don't see a problem w/ 15-40. Come winter a 10 or even 5 30 might be in order. I'm not such a big fan of the 10/5-40's as they require too many friction modifiers to reach that sort of spread..


I like to take it Easy for those first 2K miles just to be Sure everything polishes itself in perfectly.. This engine is going to be under relatively high stress all it's life..ideally give it the best chance possible of working properly for all of those miles.

After about 6-8K I'd make the switch to synthetic were in my car.

Have Fun!!!

Since the engine is NEW again I would switch to a 0W-40 OR to a 5W-40 synthetic at or before 500mi.

A few full throttle runs after 100-200 will help with break-in. NOT with any real load though. After the first oil change you should be able to start loading the engine..but hold off heavy loading for another 500mi.
