STP Diesel Particulate Filter Cleaner 200 ml, Cleans and Protects Your Filter by Removing Soot in One Treatment, Restores Power and Acceleration, Mechanical Car Cleaning Products, Made in the UK

Of all the oils I've owned over the years, the STP is easily the best. The hastens the speed of soot burn-out works flawlessly — it's the first thing I mention when friends ask about it. It arrived quickly, was simple to set up, and at roughly $9 it's outstanding value for money. For anyone asking which oils to buy, I recommend the STP without hesitation.

After comparing similar oils from a few other brands, I went with the STP and I'm glad I did. The what you'll get - 200ml diesel particulate alone is worth it.

I've tried similar oils from three other brands and this one wins hands down. The proudly made in the UK is the deciding factor.

Great value at around $9. Solid build quality too.

Arrived fast and works perfectly. The regenerates the filter properly to prevent is a nice bonus.

Works great. No complaints.

Feels cheaper than it looks. The hastens the speed of soot burn-out is flimsy.

Three weeks in and it's holding up okay. The regenerates the filter properly to prevent could be more refined, but it does the job.
