hey, i just saw a commercial for zmax and i herd its good stuff, i was wondering if anyone had any good/bad reviews because i would like to start using it in my car. its a 1993 bonneville ssei with 165,000 miles.

I personally have never used a additive for my oil. I just use a good oil, Mobile1.

Any kind of additive that makes statements it will increase HP, I steer clear of. Additives dont add HP. And in today market and advertisng standards they can say what they want without recourse. And good oil protects through it'* life cycle as good as the next one. The only additive I use is a cleaner before an oil dump.

My father worked in the petroleum business for over 30 years as an account executive and in sales. The one thing he told and I still hold to this day is that an oil additive today is what yesterdays snake oils were to the early settlers - false claims of improvement only to make a sale. If you use good quality products, stick to a regimented maintenance schedule, keep your ride tuned and not buy additives, you'll be money and performance ahead.

Remember when Slick 50 first came out? Lots of bikers decided to use that in their bikes. the problem being is that on a wet clutch bike, the graphite in the oil fouled the clutch disks and many a biker had to do a tear down and rebuild. No cost savings there!

im not really interested in adding horsepower or anything, i just want to use something that will help extend the life of my engine, something to clean out my oil and fuel system, i just want to make my engine last longer, and ideas

Do a search on the forum for Seafoaming. Lot'* of members have used the product and they believe that it does a great job of cleaning things up a bit. After using the product, you need to do fluid and filter changes - oil, fuel and trannying and depending on where you Seafoamed.

To make an engine last longer...regular maintenance, regular fluid and filter changes, never hammer it while it'* cold, fix or replace broke or worn parts as soon as possible.

Seafoam is a great cleaner just before an oil dump. Other than that, the best way to protect your engine is just to make regular oil changes. Dont let slick advertising lead you to thinking there is a better approach. The real only difference between synthetic and dino oil is how long they last. Synthetic has a little better lubricity in lab tests. Their big advantage is in they dont break down as fast. But the fact is many 3.8'* make it beyond 250K miles with just regular changes of dino.

and what about oil? i want the best possible oil for my car, i dont care about cost

Mobile 1 Synthetic.

ok thanks a bunch, thats gonna be my next oil change, is there anything special i have to do to change between regular oil and synthetic?
