So expensive engine oil really does work.

ptfe (teflon) is wonderful stuff...

not sure about using it in an engine environment though. I was under the assumption it breaks down at high temperatures?

My frying pan's good to 200c (serious question) is that enough in an engine?

depends where in the engine...

bearings are below 200, pistons probabley not

It's not such a good thing to be overheated though, or mixed into oil to be burnt later...

Polytetrafluoroethylene
Chemical Compound
Polytetrafluoroethylene is a synthetic fluoropolymer of tetrafluoroethylene that finds numerous applications.
Melting point: 326.8 °C
Density: 2.20 g/cm³
Formula: (C2F4)n
IUPAC ID: poly(1,1,2,2-tetrafluoroethylene)

I know that manufacturers were coating the upper engine parts with ceramics, and the melting point of 328 deg above certainly suggests that it's unusable in the upper part of the engine (i.e. combustion chamber area).

People crying Bs! Where's your data? Never managed to get a look at the vauxhall mag many moons ago but FF mag do good comprehensive tests and personally I would think its genuine.

it is BS

adding PTFE in a liquid will do nothing...

bonding it to surfaces is another matter altogether (where it might actually do something useful)

I believe Ford used to coat some piston rings years ago, not sure if they persisted though...

A lot of pistons are coated on the skirts for frictional reasons, and some ceramic coat the crowns for heat..

nobody adds PTFE to oil...

It's up to the person making a claim to prove it, not for people doubting them to disprove it.

And running a private 'test' isn't proof - the tester should be someone who is fully unbiased (NOT sponsored), and all test procedures should be set out and recorded clearly for the public.

Some engine builders/racers have their pistons coated with PTFE, I bought a dragbike engine that has been used treated to it, the pistons were in quite good nick considering the power he was wringing out of it

quite a common practice now, some OEM's have coatings on the thrust side of the pistons to reduce friction and wear.

It's pretty old hat. The latest coatings are Nitron MC and DLC for high load applications to reduce wear and friction. My dads work is part of tecvac who do a lot of motorsports coatings, they did ilmor mclaren engines too. I've used DLC in kart engines and the stuff is seriously impressive, bearings, bushes, shafts, pistons etc look like they could go again for double their service intervals. Engines would noticeably spin up faster due to the decreased parasitic losses of friction and therefore produce a little more power but its worth it for the decreased wear alone.

I've just used some nanodrive and there's a noticeable improvement in the engine over the long life oil used previously. In the past I have used zx1 and found that good too.

Ive has some high mileage cars in my time.
I had a vauxhall carlton 2.0 petrol, I was the 2nd owner, 1st owner was a cabbie and so was I.
In total it did 450000ish miles on the same engine.
Only got rid of it because I hit a telegraph pole and wrote it off.

Only ever had bog standard oil used in it, but changed every 6000 miles.

Tim at Opie told me (by email) that Motul X-Max 8100 was an ester based oil. I subsequently bought a lot of it as it was at a good price only to find out that it's not! After querying this and providing proof to Tim, all went quiet!

Hi

I know this is an old thread that I'm dragging up, but I've only just seen this.

The Motul X-Max was an ester based oil, then they changed the formula without telling us. Off the top of my head, I can only think of two cases when people bought 8100 from us thinking they were ester based (the X-Max and X-Lite were both ester based, then went to PAO without notification). One guy had a TT, but I'm pretty sure he bought the X-Lite rather than X-Max. I can't remember the details of the other one, but I thought that we'd got it sorted out. If it's not too late and if you've still got the emails, can you send them to [e-mail] and I'll see what I can do?

Cheers

I haven't got the emails anymore Tim but it was around June 2011! I remember asking you if I should stick with Mobil 1 or try the Motul X-Max 8100 oil. You recommended the Motul oil as it was ester based so I bought a shedload of it over a few months!
