bertj Posted May 16 Share Posted May 16 Just had my MK.8 Titanium X (125 bhp) serviced for the first time after 2 years and only 7,500 miles. I was offered an 'Engine Flush' for an aditional fee but I declined. I've now read some posts suggesting that it would have been a good idea so I'd be grateful for comments. I understand (I think!) that it's something to do with 'wet' drive belts producing debris that could block oil ways. Thanks Quote Link to comment Share on other sites More sharing options...
alexp999 Posted May 16 Share Posted May 16 Never, ever, flush the 1.0 Ecoboost. It destroys the wet built. If they offered you a flush I'd also be concerned they don't appreciate this and may not know it's also fussy about what oil is used. 5 Quote Link to comment Share on other sites More sharing options...
unofix Posted May 16 Share Posted May 16 See this thread on the same subject of the correct specification of oil for the Ecoboost 1.0 1 Quote Link to comment Share on other sites More sharing options...
unofix Posted May 16 Share Posted May 16 The make or brand of the oil is unimportant but it MUST meet the Ford specification as detailed in the owners handbook. With the 1.0 Ecoboost it is simply just not good enough to use an oil of the right viscosity for example 5W/20 Quote Link to comment Share on other sites More sharing options...
bertj Posted May 16 Author Share Posted May 16 The service was done at a main Ford dealer - I assume that they used the correct oil - the description on the work sheet/receipt is Castrol Maganatec 5W-20 E , part number 15D63B but no specification given. I vaguely remember, many, many, years ago that flushing oil was used routinely before an oil change but I was very surprised that it might be still used on modern engines using modern oils.

alexp999 Posted May 16 Share Posted May 16 A main dealer should know better than to offer to flush this engine. 3 Quote Link to comment Share on other sites More sharing options...

In my experience it is usually automatically offered by the service receptionist as one of their 'saleable extras' to generate more revenue and as they are more secretary than mechanic they don't have either the knowledge or interest to understand the needs of the different engines in all the different cars they book in and out on a daily basis.

Jim H Posted May 17 Share Posted May 17 I have seen an engine flush done on cars like Ecoboost. The only way to do it is to use clean engine oil (to right Ford Spec). It's probably expensive, but it's the only way to do it. 1 Quote Link to comment Share on other sites More sharing options...
