Engine oil additives
Discussion
I've never used Molyslip, but a few years ago, I had an Audi A4 Avant V6 TDi with an engine I thought was excessively noisy (even for a diesel). The car was quite high mileage, which I thought might account for the elevated noise levels.
My mechanic said there was nothing wrong with the engine, and the car drove OK, so I just put up with it.
Anyway, I came across an online advert for Extralube ZX1 Micro Oil treatment, which is a little bottle of additive you add to the engine oil, and it's supposed to reduce friction. It was only about £15, so I went for it.
Stuck it in the Audi, and within about a week, the engine was noticeably quieter. Still sounded like a diesel, just not a knackered one!
Haven't used it on any other cars, but would give it a go again if any of my high mileage cars started sounding a bit noisy.

Hi guys
Got a 2011 diesel turbo engine with 102000 miles on the clock
Has anyone any experience of Molyslip engine oil additives ?
Cheers

Waste of money , modern oils are very good and Got a 2011 diesel turbo engine with 102000 miles on the clock
Has anyone any experience of Molyslip engine oil additives ?

And have ballanced additives Most manufacturers
Warn against using additives ,
Best to use the correct spec oil and change
Regularly ...

Is there a problem with your engine that you are hoping to fix? If theres an issue at only 100k miles, I'd concentrate on fixing the underlying problem first.
Thank you for the replies There is nothing wrong with the engine, but I have never had a high mileage car before, I change the oils on all my cars every 3500 miles and just wondered if additives were worth it
Cheers

To be honest, 100k miles isn't high mileage these days with regular servicing. 3500 miles oil changes is probably over the top anyway, absolutely no benefit (and potential for harm) in using additional additives.There is nothing wrong with the engine, but I have never had a high mileage car before, I change the oils on all my cars every 3500 miles and just wondered if additives were worth it

Regular oil changes are good. I suppose additives might be useful sometimes, however...
If it has a DPF fitted then do not use oil additives under any circumstances. Engines with DPFs use low SAPS oil, additives add SAPS. Your DPF will block with ash sooner, especially if it's got high oil consumption.

I have always changed oil every 3500 my grandad told me when I was young always chance the oil and the engine will love you for it

You are aware of a thing called ‘progress’, surely? Engines have changed out of all recognition over the years, as have oils and fuels. All you’re doing is wasting more money than you might potentially save. There are plenty of million mile engines out there that have stuck to regular oil changes as specified by the manufacturer.

Most manufacturers set servit intervalves to keep fleet users happy by minimising cost hence why many have 18k between services these daysPersonally I think 8-12k is more reasonable
But 3.5k is just plain wasteful

Just bear in mind that Porsche, for example, have extended service intervals for the 911 Turbo S, and they’ll extend the warranty to 15 years (?). That’s confidence. A shopping car being treated like it’s a rare classic makes me chuckle. Personally I think 8-12k is more reasonable
