Just testing the water here & looking for opinions of anyone who has used this Wynns"engine flush"   in the V6 engines.

Says you add to old oil & run for 20 minutes to full operating temp & then drain  .

Then change filter & add new oil .

but it also says do not use in engines over 75,000 miles   

What your opinions guys ?





 

[henryd]

I personally wouldn't do it,could fill the oil strainer with dislodged shite

[TheBoy]

Unless you have a desperate need to flush, don't.

[cem_devecioglu]

as said, all crap will be accumulated on oil strainer unless it was frequently used on that engine..
 
not a good idea imo..

[dbug]

Personally IMO Al I wouldn't use flushing oils - as said tends to dislodge too much crap and could well cause further problems in the future.  Better a couple of quick oil changes

[Elite Pete]

Just do a couple of quick oil and filter changes

Have always used that on mine every 10k since 100k, so 13 changes so far. Not had any issues from it, but perhaps should have read the label first

Ah   someone who has been using it long term !

And if i'm reading this right yours has done 130k  since using this at each oil change & now totals 230k ?

Can I  ask if you have any cam cover failures or other oil leaks since you started using it ?

TIA    Al

I am Just following a line of enquiry / theory on the use of this stuff 

[05omegav6]

No specific oil leaks from it. Rocker gaskets done at 120k, a bit weepy now, but the car has always had a soggy sump (front crank seal mostly).

Also use it on the work Vectras as well:

Car 1, '55,  32k when bought, now 160k, bone dry.
Car 2, '55, 16k when bought, now 110k, bone dry.
Car 3, '58, 33k when bought, now 120k, bone dry.

Have used Wynns on them every service

Interesting info that Ex taxi Al     thanks

If you even begin to think that a flush is going to help cam cover gasket longevity then think again.

What will help is appropriate oil changes to stop crudd build up and breather issues.

A flush only removes deposits from the parts of the engine it comes into contact with, this excludes breathers which become clogged thanks to the gases passing through them.

The major risk of a flush is related to the state of the engine when you do it, if the inetrnal state is unknow with lots of deposits then you risk the deposits clogging the oil strainer (this has been seen quite a few times!).

[omega3000]

So if internal state is unknown we can use it but best to drop the sump and clean the sump and strainer

Indeed, although I saw a Ford engine where it seized during teh 20 mins of running with the flush in 

No need to do regularly if your keeping on top of oil changes and I never use it
