sticky gooey oil

[knighty1981]

The fact that you do it every service is fine, it's when you do it to an engine that has never had it done before. It dislodges stuff that has been there for years and can kill the engine quite quickly.

but you want to dislodge all of that junk and get rid of it ?

other thing is, I've never bought a new van, so have done it on vans with 160k on where it's never been done before!

Yes you do but in a controlled manor, that was why I said run some cheap oil through it then refill with the correct oil.

i bought my 2.5Di with 153k miles on the clock, It now has 196k miles on it and i have been flushing with 50/50 new oil/diesel every 5k miles. I drain the old oil when hot, fill with the 50/50 mix and run on tickover for 20-30 min's with the odd blip on the throttle, drain this and fit new filter and fill with clean oil. the van always runs better after a good flush.

50/50, not neat low lube diesel?... why not just add a pint of diesel to the old oil?... seems like a waste, unless you squirting that old mixture into the chassis
On some of those ADD to flush jobs, it tells you not to over rev or drive... and you're only putting in less than a pint!
Just don't think neat diesel offers enough lube protection?
