Is220D Performance

Anyone know how much the performance of this car is improved after having the new engines put in it?

Lexus are changing mine due to the headgasket problem and just wanted to know how much better the car will run..

Better MPG, Better performance all round?

Have to say in all fairness mine was very good before and the same after.

39mpg around town..up to 54mpg on a good run. Don't bother with 6th gear..utterly useless unless you are doing 90+mph.

Im getting around 32-36 and that around town and motorway, aswell as the engine overheating once i go past 100 on the odd occassion. So if i get mpg like you are then id certainly be more than happy :D

I got 32-37 before the new engine went in (which i was less than impressed with as my journey to work is 60% motorway, done 30 miles on the new engine this morning and the avg is 27 at the mo, time will tell I’m sure.

Would you go gentle on the engine to start with? Dealer told me it doesn’t make a difference but I’m sure you're supposed to keep the Revs low for the first 1000 miles?

mpg should improve after 600 miles or so. Least thats what I found.

You don't need to be excessively gentle. Drive normal I would say.

great thanks Normski

Well at least I have a faint idea of what sort of results I should be looking at now, need to remember to be faulty gentle on the engine though, I do tend to have a hard foot sometimes lol

I would read about the EGR and regular cleaning of it (every 8000 miles or so). Lots of threads here about it and vids on youtube. Easy peezy to do yourself.

Consider the use of the likes of BG244 every 10,000 miles or so, or the Bardahl equivalent.

Also consider the use of AR6200 fuel additive on each fill up. I found it helped with reduction of sooting up of the EGR. You only put in 5ml to 50 litres of fuel and it only costs pence. There is a thread here somewhere in which I gave a cost breakdown. Personally, I found it effective.

Once the car is all settled make sure you regularly give it a good run to get the engine good and hot. Need to get that DPF regenerating and get the 5th injector working. This engine does not like short runs where it does not warm up enough.

Yeah it sounds like a must do to try to keep as much soot out of the system as possible! Thanks for your replies guys

Dont quite a few people end up removing the 5th injector? whats all that about
