FAQ's: PermaTech
Below are common questions and answers. If you have additional questions simply give us a call.
Q: How does PermaTech™Oil Stop-Leak® Sealer work?
A: Oil seal and gaskets shrink over time and allow engine oil to slip by seal and leak onto the outside of the engine or even through the headgasket seal into the cylinder chamber causing blue, black or grey smoke to come out of the exhaust system. Our Oil Stop-Leak actually causes the seals and gaskets to expand back to their original size and stops the leak. This is the best method of stopping an oil leak. Store-brands simply thicken your engine oil and hope to stop the leak that way, that's like trying to stop a leaking dam by sticking you finger in the wrong side. Our method works by fixing the problem not making your oil thicker!

Q: Is PermaTech™Oil Stop-Leak® and Sealer compatible with my engine oil?
A:  PermaTech™ is chemically compatible with all types of engine oil. Including,
regular oil, synthetic and even rotella. You do not need to change your oil after using our stop-leak. Just leave it in until your next scheduled oil change.


Q: What kind of guarantee do I get?
A: Store-brands give you no guarantee!
We actually
do offer a great guarantee!  If you do not receive a full seal and stop your leak, you can simply call us to request another free bottle, (shipping/handling will apply). Our oil Stop-Leak offers a 98% success rate on the first application alone. But, if you need more just call us...

PermaTech is so powerful it easily repairs severely worn oil gaskets in any vehicle! Our Oil Stop-Leak is not a thickening agent like store-brands, so it can't increase your engines compression and cause other problems. Instead it is very thin (like water) and only targets the oil gasket and seals, causing them to expand back to their original size, thus stopping the leak. Our method and formula are superior to those store-brands and only need one treatment, (not with every oil change like the store-brands). Use our oil stop-leak sealer once, and your done!

I have a Ford Ranger which is not very old but is out of warranty it developed a really bad leak in the head gasket. Blue smoke in exhaust, overheating even misfire! Mechanic told me 2200.00 to repair oil leak in head gasket. I purchased your Permatech Oil Stop Leak, got it in 2 days. Drove it for a few days back and forth to work and no blue smoke anymore! no overheat! And running smooth! I'll let you know how it lasts.

"This stuff is awesome! I have a chevy 1500 truck that was leaking from the back of the oil pan, garage told me I need a new gasket for around $800.00. I put your permatech oil stopleak sealer in and it stopped leaking in about 3 days, the leak was so bad I was putting almost a quart of oil a week in. Worth every penny, saved me a huge bill. Thanks guys...

I have a Lincoln towncar and for months it's been blowing black smoke out of the exhaust, getting bad fuel mileage, running bad. I didn't have the money for a new head gasket job so we tried your Perma-Tech. I followed the directions and was done in about 20 minutes. Seems like its fixed it. Been driving it for over a month now and no smoke or leaks. Thanks!!"

Way to go! This stuff REALLY works! And, my car is running great (now, with over 165,000 miles on it and still running strong). No problems, whatsoever with your Perma-Tech. It sealed my Toyota Camary's rear seal in no time. Great product and great tech support. Tell Mike in tech support it worked!!!

"This is the second car I've bought lately that has major oil leaks! Last time I actually had the rear main seal replaced for almost $1000 dollars! This time I found your oil stopleak product and purchased it over the phone. Used it and NO LEAKS... I wish I knew about your PermaTech stopleak last time around, it would have saved me a lot of money. You guys have a great product!!!
