Hey guys & Ladies, has anyone used Zmax in their cars. Just saw this on the Velocity channel? Just curious of your input.

Thnx

 

I would never think of, or allow, an additive to be added to Mobil 1. Why mess with a good thing?

 

No point to use anything like that on a 430 engine.

 

Exactly!! Leave the snake oils alone. The ls430 is already the best. Just treat her right, timely maintenance, use THE GOOD GAS (93+ octane), and don't let any joe shmoe work on your car.

 

Thanks everyone!

 

no such thing as a free lunch.

There might, just might, be some benefits to this stuff, but what are the side effects/downside.

 

Completely unnecessary on the LS430. Primary benefit of that product is to the seller's wallet.

 

I would disagree but that comes from using it, not from assuming what it does and doesn't do.

Not to get into it, but read up on AvBlend for aircraft (especially helis), its the same product.

But one of the most useful characteristics of it is that it cleans up sludged oil passages quite well, and that could come in handy with modern engines and their complex oil-controlled parts like VVT systems, etc. Also useful if a car's been sitting a while and hasn't been run. An oil change, and a Zmax treatment can help flush the engine's unloved areas as the oil circulates once more. Same with the trans.

But it isn't snake oil like a lot of products. I use it about 1/4 as often as directed, for those purposes mentioned above and it works. It will NOT harm your engine regardless.

 

I always issue this challenge: When was the last time YOU had an oil related failure on an engine? Back in the 50s that happened. Now, you are more likely to have a tree fall on your car than you are to have oil problems.

 

My first new car was a 1955 Chevy. Never had, or even heard of, an oil problem with that era engines. Of course, we changed oil every 3000 miles. Now, with synthetic oils we're looking at 7000 to 10,000 miles. I've moved up to 5,000 miles between oil changes, but when the synthetic oils first came in around 1990, I only went to 3750 miles.

 

in 38 years, I have never had a vehicle where I needed to add oil between oil changes and never had any engine work done. Some of the vehicles had over 175,000 miles on them when they were sold. AND only one of those vehicles was bought new.

It's proof to me that if you do regular oil changes, you are not going to have ANY motor problems.

 

The 430 is very easy on oil. No need treat it. Not even to clean it. These engines don't use oil and hence do not dirty the oil like other cars. Those additives have potential for dirty engines that use oil.

 

Worst car by far that I ever owned was a 1975 VW Rabbit. Despite working at least part-time all thru school it kept me perpetually penniless because it broke down every other month I owned it. By the time I traded it in late 1979 after I had graduated and saved some money, it had apprx 60k miles and the valves were shot, burned a quart of oil every 300 miles, smoked like a mosquito truck. In the 3 years I owned it I had to replace the distributor, steering rack, multiple front suspension parts, brake lines rusted out inside the car, AC went out, other items I can't remember. It was an unmitigated stinking POS. Permanently cured me of ever owning a VW.

 

That was my first car ! Funny how our experiences differ.
Bought it used for $ 3,000. Never broke. Sold it 4 years later for $ 3,500

 

That's amazing. I can't imagine a 75 Rabbit not breaking at least every other month. I did have a friend who owned an early 80s version of the Rabbit that was reliable. Good for you. I would not wish my experience with that car on anyone. I owned mine in Chicago and it was always parked outside through 4 very harsh winters and lots of road salt. It seemed especially prone to rust related issues...muffler, brake lines, fenders, etc.
