Why put engine flush in? You not going to remove it before it goes on the rollers???? I have never used engine flush in my car and Mark @ Saxon Motorpsort commented that he hasn't seen a bottom end so clean before (expect a new bottom end).

All I do is change the oil after every trackday or 3months which ever comes first and make you feel better the oil I use is £50 for 5 litres! :cry:

With the petrol you might as well run it on what ever petrol you have to see what power you usually have, I've always filled my car with super unleaded or now I'm commonly using V-Power from Shell as it's the closest petrol station to me and the prices are the same as tesco..... the joy of living in the valley's :)

It will take a few tanks fills for the ecu to adjust itself to the new higher octane petrol

just use VW stuff, it's £25 for 5 litres and £4 odd for a fuel filter! I'm using more expensive oil because of the oil temps I was getting out on track and it rev's more, with more power, etc.... Start looking into engine oil and you become scared and think what damaged you done etc... there's a lot about oil.

If you use engine flush you will need to change the oil as all the crap it collects need to be removed.

i should stop using tesco petrol, that will give me some power back. drained some off a car today, it wasnt even blue-ish at all. was clear as water.

If you read on the tin of engine flush it tells you to put it in the engine before a oil change and drive the car for a few 100 miles or so and then change the oil. All the crap it removes from your engine is at the moment sitting in the sump..... should then change the oil to remove the sh!t from your engine!

Rather a lot of work for "one day" just keep changing the oil, after a while to oil coming out will look like the new oil going in!
