It may be "way better", but it's not to the Suzuki engine specs. They recommend 10W-40 up to 20W-50.

Try putting the recommended oil in and see if that helps.

I emailed Suzuki UK them selves as most online places have it wrong

Suzuki for the UK rec 5w30 syth API SL, do not reccomend SM onwards.

They may have charged for it but never used any

Re : Gearbox Oil

OP says he supplied it !

But it may be that they never bothered putting it in

Cambelts are always in the manufacturer service schedule as requiring replacement at some point, but often gearbox oil is just a check every x years rather than specified to be changed.

Alas that doesn't help the OP. 5w30 should be just the trick for a vvti engine. Is it possible the engine flush has caused this problem? I agree, manufacturers dont specify it - it's just a money spinner for the garage.

to be safe I swapped the oil again a week later my self.

5 weeks later, this engine is not sounding quite right, not bad but not 100%, the temps have now dropped as winter coming, start up is a bit rougher than I would expect.

I take it back, says somthing is not right, he checks it during the day, runs it up to temprature, I collect it, he says there's nothing wrong, he can hear the fuel injectors but nothing is wrong.

When did it stop running right?

you didn't say it wasn't running right when you got it back, just 5 weeks after you changed the oil yourself.. so it might have nothing to do with the flush.... or their service.

i think they meant they may have charged for the flush but not used it.

Unfortunately any case you might have ever had disappeared when you
'swapped the oil again a week later'.

If I were Mr. Garage Owner, I'd simply say "it was fine until you messed around with it. Bye".

paranoia over the flush and "did they use my oil, or did they just put the cheap stuff in?" made me change the oil myself, just wanted to make sure non was left in and was in the right oil.

about 2 weeks ago it started not sounding quiet right.

we're upto just short of 1000 miles since the "service"


sufficed to say I have now located a self service garage near to me so I can DIY the hard jobs now.

Oh, I have kept 1/2 a litre of the oil I drained out after their service btw.

I seriously doubt that would make a blind bit of difference. There's no chain of evidence, so who's to say the container in which you've kept that oil might not be or have been contaminated with diesel, or water, or ammonia, or engine flush, or wee? Any garage owner would challenge you to prove that the stuff that came out was beyond reasonable doubt the stuff that's in the container, and you won't be able to.

Sorry, but I genuinely think this is one of those 'tough luck' moments.

I mean, it is *entirely* possible that actually, they did NOTHING wrong apart from suppy an additive you didn't ask for, which in no way has had any effect on the car. Especially when the only evidence is 'it sounds a bit funny'.

Irrespective of people's personal opinions of engine flush, thousands of people do use it day in day out, and if it were really that harmful, don't you think there'd be more of a fuss about it?

If it was really harmful at all, people like Lucas Oils (who have a rock solid reputation for quality every bit as good as Fuch's) wouldn't be marketing it in the first place.

Flush may be harmful if misused but that applies to engine oil itself - leave it too long before changes (or even change too frequently according to some studies), over / under fill, use a seriously wrong grade, or pour it into the cooling system instead of the sump and it'll be very harmful stuff. Use the stuff (oil or flush) according to the maker's instructions and it may be pointless but it won't be harmful.

Funny noises and "not quite right", on the other hand, can occur at any time. You would't believe the number of customers I have who's watches can't be seriously broken because they were "working fine before it wasn't"!
