EDT Engine Treatment - Anyone Done It?

Turbo Tony · #1 25th May 2016, 05:25 PM

I've been speaking to my local-ish EDT franchisee about having the EDT treatment done in my cars.

For anyone who's not heard of it, the process involves draining all the oil in your engine, connecting hoses to your sump and your oil filter housing and then pumping heated soya oil through the engine via a filter that removes all the gunk that's been building up.

A very OCD friend at work had it done on his TT and he had great results - he's singing it's praises, so I thought I'd give it a try.

My nearest place is Full Circle Services in High Wycombe. When I mentioned the car, he said they'd done one on the same car recently. Was it anyone on here?

I've asked if they would do a before/after emissions test so I can post the results online and they seemed fine with that. They're an MOT station, so have the emissions equipment in-house.

EDT is amazing. I work in a main dealer for Ford/Fiat/Seat and Kia. We used to offer it for customers during service. The uptake was poor as most people felt they were being pressured into it and we ended up giving up the machine.

However the results are amazing. The crap it catches in the visible filter is unbelievable. My oil was still clear and yellow after a year and 8000miles. The same for each customer too. We used to drain the oil a year later and it would still be clean.

It has various things to consider, especially for older vehicles or vehicles prone to oil leaks, since it removes any build up that could be hiding a leak, or quietening noisy components. Otherwise for visible results it's ace. I'd have it done every year if we still had the machine.

Definitely not for me:

1. There should not be any sludge or varnish build-up in the engine if using decent oils, changing regularly and not overheating it. Any modern oil contains detergents and solvents that keep the dirt floating dissolved in oil and does not let it settle out. Bigger particles get trapped in filter of course.

2. Even if there was any varnish or sludge build-up due to poor oils, servicing or overheating it is unlikely that 15 minute procedure will undo years of build-up and there would be risk of it coming off in lumps. I have seen many times in Latvia in 1990's when after coming out of USSR western products started coming in including engine oils, many people used them better oils lifted up varnish that has built up during poor Soviet oil use, it was often coming off in lumps and sometimes blocking oil channels and wrecking engines.

3. I would also be worried about using vegetable oil in the engine as the seals have not been designed for use with it. For example running biodiesel and vegetable oil in older diesel cars can dissolve seals and hoses in the fuel system as they were not designed for it.

I would vote for using that money for more frequent oil changes or you can even do 2 changes at the time if you want. Change the oil, run it for 15 min or go short drive, do another oil change. You can get Quantum Longlife III oil for about £80-90 for 20l which is enough foe 2.5 changes.

The difference with the EDT machine is the level goes above the normal oil level so it clear crap that normal oil changes cannot clear. The results speak for themselves when removing the EDT filter.

Yes a well looked after car may not benefit, but if you're unaware of the service history or previous owners, it's a good thing to have done.

Thanks very much for the posts - that's two very different opinions.

As my car is a bit an unknown (I've only had it for a few weeks), I think I'll do it so I know where I'm starting from.

I've had my previous cars Terracleaned and I'm considering having that done too to help remove the carbon deposits that may be choking the engine. The guy I use for it is going to look into getting hold of the adaptors that will also clean the backs of the valves that can so easily get gunked up on an FSI engine.

Anyway, my car is booked in for the EDT and the garage has agreed to do an emissions test before and after. I'll post the results!

Make sure you keep the tube oil filter from the machine afterwards. It's a bit like the 'sausage floats' that you take swimming. The results speak for themselves. Whilst I love a terraclean, or fuel additives or using premium fuel, this is the only 'thing' that has physical results. Your emmisions will probably remain unchanged since EDT works on the oil side of the engine. In a years time, I guarantee that oil will still be pretty much clean when you drain it.
