| Slick 50 Teflon Oil Treatment |
|
Another technical issue related to lubricants.
Recently I used Slick 50 Teflon Treatment in my wife 240 GL Volvo - an old one - on the recommendation of a fairly smart engineer that does some work on my vehicles. His point of view was that the claims of Slick 50 to "bond" to the metal etc were garbage however it would quieten down the valve train and the engine would run better. This is exactly what has happened.
Now the TDV6 has a "sintered iron" construction and I was wondering if given the porous nature of the block whether Slick 50 might be worth while putting in the motor. Possible issues that I could see with the product are that the Turbo lubrication might not like it and/or using it too early might cause problems bedding the rings in properly. Rather interestingly when aircraft engines are rebuilt one of the issues that causes poor engine life is not running them in properly and in fact the requirements for those engines are to run them at quite high cylinder pressures and power outputs to make sure they bed in properly. Then to change the oil from a thin bedding in oil to normal oil at a specified changeover interval.
Anyone got any comments ?

I wouldn't do it with the D3, but I have in old Landy's. Modern engines are somewhat different.

I've never been convinced that the 'running in period' of a vehicle engine is beneficial, used to work for a company that overhauled generators, it was standard practice to run them at max load once the operating temperature had been reached, we never had any problems and got quite a few jobs sorting out lightly loaded engines, usually a decoke and deglaze sorted them out. I'd be wary of anything that may potentially affect the lubrication of the turbo... it is the hottest part of the engine after all

I rebuilt the engine on my 2a a year ago. My running in period consisted of;
1. 30 minutes warm up to check for leaks
2. Fix the leaks.
3. 50 Mile drive at low speed
4. Drop the oil, and replace with running in oil
5. 500 miles at normal speeds, avoiding excessive revs, but used the torque of the engine as much as possible on hills
6. Another oil change.
The engine now runs very nicely, and uses no oil, which is good for a 1966 engine.

Using the Torque on the hills while neither lugging or over reving is exactly what will keep the pressures high. Is running in oil still available in the UK because I have not seen it here in Australia/New Zealand for a very long time other than the Aero Engine stuff?

not seen it for a while but not looked...  it should be available, although we used to make our own with 5% kero  to the oil recommended for the engine *note I am not suggesting anyone uses this - historical (hysterical?) comment only*

It is available, its made by Millers oils, and comes under their "Classic" brand. I get it from Moss, who are a nationwide distributor of British sports car spares, I get my MG bits from them.

I have just picked my disco3 SE Auto 2days ago. I'm going to keep the revs low. Can anybody tell me any tricks on running in, as I might keep the Disco along time.

Take it easy for few thousand miles, get an oil and filter change done before the first service, I changed mine at 7.5k The End
