I heard someone has a 375bhp Evo 7 with 130,000 on the clock...no mechanical problems and apparently sounds as good as new. Service history and condition of the engine are more important than the overall mileage. Mileage and engine condition are not directly related.
Which I don't have. The extra torque produces extra stress, blah blah blah. 1+1=3.
It may be "wrong" but often things which aren't "prescribed" by manufacturers, etc, work in a beneficial manner.
Yeah, I appreciate it can affect things, both negatively and positively in terms of combustion; but in the quantities applied (we're talking 250ml per 52-55l of diesel, it won't make a difference. You could quite happily put 2 or 3 litres of petrol in with 50L of diesel with no issues; I wouldn't recommend it but if you accidentally fill up with a couple of quids worth of petrol you'll be OK! I think they stopped 2 strokes on the road due to emissions gubbins anyway; the last remaining torch carrying the 2 stroke flame were bikes/mopeds such as the RS125, Derbi, etc, and they've all been forced to go to 4 stroke unfortunately. I think lawn mowers, etc however are exempt but I don't think I'll see one on the A34 any time soon.
Yes, BS EN 590is the standard diesel specification - There is no mention of 2 stroke oil however what is the harm in trying... for example when cleaning things like the variable nozzles and intake manifolds, and EGRs - you can buy a specific cleaning kit (such as Innotec) but people have found that Mr Muscle works really well too.
I'm aware it's not "recommended" by manufactures but my car is not under warranty and has done nearly 120k so what's the harm? Oil changes every 10k should mean all things considered it's got a lot of miles left in it regardless of whether I run 2 stroke oil or not.
Which I won't be when I try the BP Ultimate; plus I've found no tangible benefit in 2 stroke oil so likely won't run it agai.Jibber, I challenge you to find one thing i've said regarding this which is wrong. It's things I gained knowledge of first hand...so no.
Will bear that in mind thanks
Regardless of what their use it for - Dual mass flywheels are used in loads of diesels and other performance cars (petrols inc) even up to the 335. However torque delivery will cause the diesel DMFs to fail more than a petrol. Which is why they generally fail. Mine was OK touch wood until about 4000 miles after the remap when it started to give an aggressive thud when accelerating from low RPMS (1500rpm in 4th for example). My Dads car was standard and had done 78k when it failed. My friends car is a brand new 61 plate Corsa D which occasionally has the feeling of a failing DMF and it's only done 3500 miles...
An excellent suggestion.
They are in the grand scale of things. Aside from intial taxation purposes in diesels, they serve no purpose. Diesels are not tested for emissions, they are tested for smoke. Environmental reasons I'm not getting involved in as I don't care how many hydrocarbons my car emits. The warmer the better in my opinion so I welcome global warming. I'm sure Racer_X can provide further info.
Yeah you're right.
As soon as some clever people come along, I'll be happy to do that.
Again you think you know me oh so well. It was Fully Synthetic Castrol GPS. I'd never put any Halfords/Supermarket branded oil or vital fluids in my cars... I only used it because I found an old bottle from when I accidental bought 2stroke instead of 4 stroke for my Triumph. Luckily I noticed before I put it in the bike.. It was a month after buying before I got a chance to use it, so I couldn't get a refund. I had read some positive reports of people using 2 stroke oil as an additive in diesel so thought I would try rather than throw it in the bin.
I did check my fuel filter a few days ago to see if it was clogging it up but it was actually very clean still. (I fitted a new one about 1200 miles ago) just before I started running 2 stroke oil as an additive. As I said whether it worked or not was one thing; it's certainly not going to cause any more build up than it would with ordinary diesel.
'twas Tristans suggestion, why don't you pass that advice to him. Some people on the forums say it reduces smoke and they notice a smoother idle, I will try it for myself and find out. Either way it'll do it no harm but then again what do I know since I am not a chemical engineer. And anyway it's only £3.50 more per tankful so no great loss either way. It'll either work and I'll be happy or it won't and I'll go back to supermarket fuel.

he was jack. the z4s do it in 0-60 in 6.5-7 second, i can consistently get 7.8 time after time. so maybe he missed a shift or got a bad launch but i was quite proud.
Diesels are not tested for MOT purposes so after the initial type approval test emissions are pointless. They have a visual smoke test.
Regardless of what you think I have seen that EGRs and DMFs are both pointless and prone to failure so I think (thus my opinion is valid) that it's a bad idea.
2 stroke oil is combustible so it leaves no more internal residue than regular diesel would. You could run a 2 stroke engine on diesel oil if you wanted actually. And yes, laugh at my car which has been remapped. Obviously you've never had a "before" and "after" of a turbocharged/diesel car with a map. I get about 6-7more MPG (an extra 80 or so miles per tank, best before a remap was around 535, I can regularly get 600+ now and my driving style hasn't changed) plus a dyno proven (awaits your comments about inaccurate dynos) 149bhp, 48bhp over standard, plus torque went from about 211 to nearly 270. I raced a 2.8 Z4 and had it to 70mph. Enough said really. It's about the same as a clio 182cup which isn't a slow car. Anyway I couldn't care if you sit there going ha ha ha ha. Hard to take a life lesson from someone who enjoys stuffing his face with jaffa cakes.
Tristain, DMFs do fail unfortunately. And it is a common occurance
I agree those people who think removing EGRs increase power are a bit of an idiot. Luckily I never mentioned any power increases, nor increase vibration rrom an SMF.
The "Death rattle" I refer to is this - I actually wish my single mass flywheel made this noise.
Generally, the inlet manifold and the EGR get clogged on many diesels, especially considering the peoples cars on the forum aren't exactly driven...slowly..shall we say..it's either the fuel or the actual system. Considering diesels are not tested for emissions, the whole point of having an EGR is pointless in my eyes. They serve no practical purpose, what benefits do they bring...cleaner running? Not really, better economy, no...all they really do is break/get clogged up.
Unsure about the whole "superfuel" myth though, I've been running about 250ml of 2 stroke oil per tankful for the last 1200 miles to see what happens, not really noticed much improvement, infact any - at least not audiable. I presume it's providing slightly extra amounts of lubrication to the top end but we'll see.. so next fill up I'll be using some BP Ultimate diesel and run that over a couple of tanks.
I remember when I had my car remapped I had it on Ultimate diesel then and it felt like it was flying so I'm hoping the fuel will improve things such as noise and take away that last bit of smoke. I normally fill up at Sainsburys because I get Nectar points but then I realised BP do those as well. :>

Far from it, just every time I post anything mechanical Alex has to try and "get one over". Anyone else, I couldn't care. 
Oh **** off Alex you pretentious twat.
You think you are so clever, so what you study mechanical engineering, I don't. Big deal. Does that mean my opinions are invalid?
I'm a member on one of the largest forums in the UK (ukmkivs.net), which if for VW Golfs if you're not clever enough to work that out - and pretty much all the Golfs come with EGRs and the diesels come with DMFs. My car came with a DMF and an EGR.
Failure of DMF is not a question of if, but rather when. Every single person I know has had it who has a diesel, plus about 65% of diesel owners on ukmkivs.net have either had to already change their DMF or chose to replace it with a Single Mass Flywheel. I have done the latter, along with an uprated clutch to take more power. My car idles, with a Single Mass Flywheel, with almost no audiable difference to a regular dual mass. There are kits out there with damper springs which in effect do the job of the dual mass flywheel but on the clutch plate itself.
There are no additional vibrations and no death rattle. The Helix and Sachs Stage 2/3 kits are noisy but the payoff is increase clamping force and personally I think if my diesel were pumping out 200bhp+ I would want this death rattle as it's part of the character of the car.
As for the EGR - Let's see, mine was getting clogged, not enough to cause problems, (I do quite a lot of miles so it's hardly sitting in traffic, run a trusted fuel additive as well and up until I stopped doing this I hardly had any smoke on full throttle) but enough for me to notice until, as I said, it was disabled and it cleared itself out. The slight stutter at idle which was always there when warm disappeared after the EGR was mapped out as well.. I checked it a couple of weeks ago and you can almost see the metal on the inner wall. P
Most EGRs look like this...you tell me this is the product of an efficient design..
Most people again on the owners forum, both petrol and diesel, have suffered EGR issues. My Dad's car (07 Lexus IS220d) was in the dealership receiving a full engine rebuild for 7 weeks in total, because firstly the EGR caused limp mode and had to be replaced (would have cost £800 if it wasn't under warranty) and then a few weeks later, the DPF broke due to contamination, partly due to a work piston ring and this was also attributed to the build up in the EGR that caused his car to go in to the garage before. I should add it also had a replacement dual mass flywheel due to vibrations and noise..funny that. In total over £7000 has been spent on warranty claims by Lexus UK. And that's for the engine rebuild, flywheel and EGR. Yeah, these items are clearly good.
So in short, Alex, who needs to have done an apprenticeship in a garage, when you have enough knowledge to get by and have the first hand experience of these mechanical parts.
In short, shut your face.

All EGRs do is get gunged up. I've had no problem with mine because it's controlled by software and I had it mapped out, so it's in effect not being used, I will remove it at some point. when it got mapped out it was quite messy. thankfully it's cleared itself up now since it's been removed from the combustion cycle as i said.
7/10 times if your car has poor power, bad throttle response, poor fuel economy, especially if it's a diesel, it'll be because of the EGR. EGRs are like dual mass flywheels. in principle, an excellent idea. in practise, crap.

EGR is quite possibly one of the worst devices fitted to an automobile in the last decade.
Highline cluster for my car. This isn't fitted yet, getting it fitted on Saturday.
16 or 17 or somethiing kill streak yesterday. pp90m1, rapid fire, silenced, fmg9, akimbo - slight of hand pro, assasain pro, steady aim pro.
the normal attack killstreak thing, at 3,5 and 7. managed to get 3 predator missles and 2 attack helos. pwnage

Not fixed because my PC would struggle to play it at decent graphic levels. I need moar RAM and a better GPU.
**** off. fat people are cool
i can just see a car park and a few lights don't you people ever take photos in the daytime? a black car in a black night good goind.
no i probably won't be using them again. the guys who did this are my normal garage for servicing and fixing etc.
during tyre changes on my new wheels i would say "here look there's no marks and if there are marks on them after a tyre change you can pay for a refurb". i doubt they would scratch the new ones.
you shouldn't mark wheels at all if doing it properly though, i used to do tyres on motorcycles and there were rubberised lips not metal.

yeah tyre shop damaged it putting tyres on, they are 185s and the rim either 6.5 or 7 can't remember (either way designed for 205s).
they are winter wheels which i painted myself thus not too bothered. if it gets really bad i'll touch it up but yeah.
