Extending engine life from wear caused by blowby. We have found minimal products that really make a difference when adding to oil. That is why that after 15 years with this Certech Gels technology we were so impressed that we wanted to put it out to other engine owners. If you have blowby, that means there is ring and cylinder wear that can be reversed by ceramic resurfacing. That is want we do. AND if it does not work for you, we refund your money.
