Accord 2.2 i-ctdi
Hello ..What is everyone's thoughts of giving there Diesel engines a oil flush ..My Accord only had it 3 weeks and has done just over 73k miles and I will be giving it a service soon ..Do these engines require an engine flush ??… is it recommended or best to not do this ...

Regards
Wilson
 
This Accord has only done 73 k miles and has good service history. I did look at the oil link above But there was some issues due to delivery to where I live ..I don't live in the Highlands of Scotland yet courier seems to think this and theres a extra Surcharges..I thought this type of problems were sorted out ..

Not necessary unless it's a high miler with unknown or irregular service record.

I would check the oil that comes out after a run before draining, in case it is proper sludge/has metallic bits/smells of bananas. Leave overnght on a level road to make sure as much as possible comes out and sift thoroughly for any debris. If you have a magnet on a stick this helps

If the pan shows any of those things then before changing the filter, put a cheap 20/50 in and idle/run gently for ten minutes or so, then drain - before filter change/filling with the recommended stuff.
 
Just jumping into this thread. My 2.2 cdti is just shy of 200K miles. Oil is changed every 6 months and I use the recommended 0W30 oil. Will the engine now perform better if I start using 5W30 oil?

A cheap 20/50 will do no benefit.

If you want to flush then use the specified 0w30 and then drop it again after 1,000 miles. This means the high quality oil will collect the 'dirt' from around the engine and it will then drop out with it when drained. A cheap 20/50 will not contain the high quality additives required to do this.

The cheaper oils out there have a good detergent level, once warmed up sufficiently the new oil keeps all manner of soot and debris particles in suspension which will be extracted when drained. Again leave the sump plug off overnight if possible (and remove the filter this time round - I also turn the engine over once to empty the oil pump chamber and pipes, just personal preference)
As long as you avoid grades designed for older engines, usually the expensive ones, the engine internals will be far cleaner, costing around £15 and an hours work.
 
Forgot to add, oils designed for diesels will have a higher detergent (BN / alkalinty number) - and dispersant capacity than petrol versions, so always choose one of those.
