Slick 50 saves XR2

About 45 years ago I had an XR2, I used to check oil and water levels regularly, I had lent it to my brother in-law for a few weeks while his car was in for repair, I got it back it must have developed a slight water leak which it ran short of water, out on a run it seized up while at a junction, we towed it home, when it cooled down it started up again and sounded fine.
I was not happy so I took the head off to find that the pistons had not picked up at all and there were no marks on the bores. In my mind it was "Slick 50" that saved it.
I was a ford mechanic at the time Read full review

Great deal

Superfast post.
I've used this additive in several motorcycles and cars: they have all clocked up high mileage with no problems. I stripped a ducati engine with 125,000 miles and the bores and pistons had almost new tolerances.
Makes my porsche 911 run 2-5 degrees cooler too!
Great price too. Read full review

Well worth using it

I have been using Slick 50 for years and the coating it leaves a smooth surface so the internal moving parts don't wear so much
