Check out the postings by one George BOSCH (user name hgbosch on 4x4 Community Forum who promotes the use of a PTFE additive by brand name. He has a copy of a Polish report that seems to indicate that the product he refers to does NOT clog or aggregate particles so that would be an advantage.

As the owner of a brand new TDV6 engine (mine failed ingloriously at 142 000 km) I am reluctant to do anything other than increase the frequency of oil and filter changes. To achieve that I am currently replacing both at 6 000 km and always use only OEM filters and fully synthetic oil meeting or exceeding the original 5W-30 specification.

I would suggest that if you are in any doubt about the oil used in your engine then get it assessed. I used CAT (the bulldozer and heavy machinery mob) here in Brisbane as they supply a kit to sample and send by return post; IIRC it was about $45 but well worth it for peace of mind.

Works great! Should ruin your engine in no time flat...

Avoid it...

Of course they will claim it is different stuff.

How to blow any warranty on OEM, reco or transplant motor - run PTFE additives. Once found in your oil galleries or tested oil sample its all over, Land Rover......

In particular aftermarket warranty companies are always looking for a way "out" of a claim.
