About this deal
Put 1 bottle in the rear end differential so attempt to stop a very minor leak around the pinion seal. Another person, a car mechanic of over 50 years, to whom I also subscribe said, based on his years of experience, that the ATP TP-205 product was the best even though it was somewhat expensive. Of course, you won't make your friends too happy if you park your dripping British pile in their nice clean driveways.
He compared the different manufacturer products showing how he tested them and the results he got from these tests.
I totally agree that of all the plethora of moose pee additives out there, this stuff is actually effective for softening/restoring seals.
The best thing to do with rubber suspension bushings is leave them alone and when worn out replace them, that's it. It's slightly better than before I used this stuff, but really not worth the time and money I spent applying it. He either hates Nissans or loves Volvos or thinks electric cars are trash or moans about transverse mounted engines. Oil Saver completely stopped the leaks on my father's Taurus (though after me driving quate a bit more than he has in recent years).Since this car has around 80TKm on it and never saw extended oil change intervals I suspect one or two of the oil brands I used shrank the seals. You can see in the attached photo is is running down the differential housing as the drive shaft spins. Helps to preserve and prolong the life of rubber suspension bushings and other rubber based components.
