Bor Katkısı ¿

I received this email from Albert Clark who has, it seems, had first-hand experience of one of the additive products:
I kept hearing about such a product and found a store going out of business that was practically giving it away. I put a quart in two cars: An MGB and a Chevy 305 V-8.
The MGB went 20 miles before a ring stuck causing it to start throwing oil everywhere. A mechanic then messed up when putting new pistons on the old rods and shortly after rebuild a piston froze and threw a rod bearing that ruined the crank, etc.
The Chevy started using a quart every 25 miles immediately after the product was used. I drained it and refilled immediately, but it took engine flush and about 4 oil changes over 2000 miles before oil usage was reduced to a quart every 400 miles. It was using a quart every 800 miles before that. I ended up putting another 60,000 miles for a total of 180,000 miles before rebuild.
I will never recommend such a product to anyone.

The moral? If you're going to care for your engine, do it properly, not in half-measures, and it will look after you for as many miles as you care to drive.
