I had looked everywhere for an oil filter wrench that would fit the cartridge filter on this1999 Volvo v90 XC AWD. Nothing local worked and then there was the issue where the recommended filter wrench slipped. When I was ordering the 86.6mm wrench, I looked at the pictures and noticed it said if I had a specific type of marking on the housing then I would need this 86.4mm wrench instead. Thanks to that bit of info I can now replace the filter. Works 100% like a charm and filter was easy to remove with a standard ratchet. Wrench seems well made and the price was perfect, especially compared to some of the others that are $35+. Very satisfied with this purchase.

Liquid Molly engine flush simply works.. Put it F 150 and eco boost with the chain rattle. Followed the instructions. A week later they rattling stopped. Scene clean all the sludge out.

what a difference !

Note: there are no English instructions. I wanted this cleaning agent to disperse throughout the nooks and crannies of the engine, so about ten minutes before arriving at the mechanic's shop for my oil change appointment, I pulled the car over and poured this into the engine, then drove it the rest of the way there. The mechanic reported lots of sludge drained out with the oil. The engine seems to perform and sound better, as if it's not working as hard.

Buen producto

Buen producto, limpia perfectamente el motor interno y se libera la suciedad en el cambio de aceite. no use todo el contenido, creo que es bueno usarlo en 2 cambios de aceite para una mayor eficiencia.
