I found this web site yesterday: www.synlube.com . Has anyone heard of this or used it? Looks very interesting. I've not used any synthetics before. Your thougts on this?

 

You can make this stuff at home. Use 1 qt Chevron Supreme, two qts Redline, two qts Mobil One Extended 15,000 and one qt Amsoil HDD in your favorite viscosity. It pretty much has everything you find in a variety of oils but not much else. The claims are ridiculous at best. If you don't have a NEED for syntheitc oil there isn't much advantage to them anymore. The dino oils have improved dramatically over the last several years but the synthetics are pretty much the same-o-same-o. Your money and my .02

 

Well, they claim there's a little more than that in there Flash. "SynLube™ is a synergetic blend of man-made liquid and solid chemically inert lubricants that are thermally stable from -65°F (-54°C) to over 500°F (260°C). The sub-micronic particles of Graphite, PTFE and MoS2 are colloidally suspended in a mixture of synthetic liquid lubricants."

Lets see, they claim it has Graphite, Teflon, and Moly Disulfide! None of these belong in motor oils.

SynLube is a scam, pure and simple. Flash was exactly right, their claims are rediculous at best. If I may add, their claims are dangerous, as is their product.

 

rusty molybdenum disulfide is widely used in lots of oils with no ill effects. i think you are thinking of the solid moly. which should not be used in a engine. the solid moly is what ruins engines. like cummins found out about 8 years ago.

 

Oh, gosh! And it only costs $40 a quart! I'll bet this oil does an outstanding job at what it was designed to do best... parting fools from their money, LOL!

 

Thing is, gear oil can already be 'lifetime' with any good synthetic gear oil in not severe duty application. And even conventional ATF can also easily last for 100k or more in many cases. So there's really nothing extraordinary here, especially with gear oil, and that leaves motor oil.

Since they have a separate initial fill, service oil, and add-in oil, the later two, but especially the add-in oil can be used to replace depleted additives, and their "microglass" filter can remove smaller particles that can keep the oil clean for longer.
However, I see 2 major problems, even when giving them the benefit of doubt elsewhere:
a) the filter will most likely fill up well before the advertised 150k, so it need to be changed anyhow, or risk engine damage.
b) with various oils costing $22/$32/$40 (!!!) I don't think anyone is going to save any money by switching to synlube.

 

As you can tell I didn't bother to read their psycho-babble and missed the "other" ingredients. Forgot about those considering I haven't heard anybody ask about this stuff in awhile. The moly used in todays oils is the molybdenum trialkydithocarbamate better known as MoTDC. The moly disulphide was the black crud used in the 60's that didn't work as it spent most of its life in the filter. It works great in a grease though but despite the claims of smaller particulate size and better stratification in the base fluid- it still don't work. I have seen several Lube for Life systems. The best in my opinion was a unit that had a filter the size of a bucket. There were time release additives and acid neutralizers in the filter. The fluid used was a PAO and ester mix but was proprietary in its composition. The life as I know it was around 50,000 miles. Not bad not having to change oil for 50,000 miles. But them again, we wouldn't have anything to talk about if it came to reality.

 

Change the oil? You mean you're to change it? What does it change into?

 

I found this thread by accident but I thought that I'd throw my 2¢ in since I've been using Synlube for 8+ years now. It does work. I have a 2004 Ford Ranger FX4 and by any measure of performance I am completely satisfied. I have averaged 133% of the EPA fuel efficiency estimate for this truck and have consumed about 4-6 ounces of oil. The sparks show normal engine operation and the tailpipe is free of carbon. It looks about as clean as the day I got the truck. Other readers can choose for themselves whether they wish to believe in the speculations of those who have no practical experience with this product or someone whose truck has used this oil for over 53K miles.

I'm pretty sure all of those are used in motor oil additives.. Slick 50 has been around for longer than I've been around and it uses teflon in it.. Why do you think they make teflon coated pistons,, bearings,, hell anything.. It lubricates for much longer than minneral oil and resists heat much better. And my grandpa has been an engine builder for over 50 years using moly disulfide in the oil to break in every engine he builds with only good results... Now the claims I think are a stretch of the truth a little, but my uncle did have an old ford dump truck with a 300 inline 6 with over 500,000 miles.. He said he never changed the oil in it just added slick 50 every time it needed oil, which was minimal. He did have a remote filter rigged up that he would clean with diesel about every 15,000 miles though.

 

Talk about digging up the past.

 

Ooops, Put wrong reply in this post.
