Silverhook SGA07 Stop Smoke Oil Treatment 450ml

Very sceptical about stop smoke products although this has worked on my r56 mini which have a reputation for valve stem seal issues and smoke on idle. This has cleared my smoke up for now, long term i will meed the seals changing but for now its done the trick. Last 3 mot using this at oil change no smoke mentioned. Previous to using this had smoke on acceleration advisory twice

A brand you can trust. Great value and quality.

Was getting 46mpg in my RAV4 D4D 2.2 and some black smoke during hard acceleration. Added this and no smoke and mpg hit 60mpg. I was taking photos of my mpg readout and odometer haha how sad. I’ve done around 1000 miles since adding it and some black smoke has come back and mpg is now around 53mpg (which is still impressive). Even tho this seems short lived It has still saved me many times the purchase cost already. Very happy customer

Followed the instructions to the letter but this product does not do what it says. Maybe did not just work for my car. Would not recommend look else were

I have an older high mileage van I use daily for work, it would smoke when underload or driving above 3500 revs, now it's completely clear, van is more responsive and my mpg has improved. I will definitely use again, people saying that it didn't work for them I would suggest it's a more mechanical issue like injector seals etc, but for me it's helped massively

Not brilliant, didn’t make any difference to my car

Great product significantly reduced smoke from my engine excellent

Brilliant product.... my 2003 van started smoking badly... white smoke!!! Was burning oil.... used this exactly as per instructions and it has totally stopped all smoke..... will definitely buy again if needed
