my friend has a Tornado in his 87 4-cyl coupe and had it in there for quite some time and he said it works great and you can feel the difference immediately. ZMax is suppose to be bad. It contain chemicles that do long term damage. ZMax is a temporary fix and your suppose to add it like twice a year but a couple years down the road you'll start having problems with your engine. If there was any safe way to improve oil, then oil companies would have done it by now.
