Many guys will bag me for this as they're not fmailiar with the product and anything not familiar tends to be treated with suspicion... and that's fair enough.
A while back I was asked to address the nations top engine builders about a new break through in oil technology that I'd been fortunate enough to become associated with for a time. The break through was not via one of the big companies but via the scientist who developed the new rocket fuel which NASA now use, and which saved 20% on fuel during rocket launches.
Oil companies have had a problem in the past with film strength and maintaining an adequate TBN (Total Base Number) which refers to its alkaline reserves... the bottom line is that the most slippery additive used to give film strength by Oil Companies is traditionally moly (abbreviated). Moly is good for about 100,000psi loading. Sadly, a good aggressive cam grind can generate loads on the lifter up to 160,000psi!!! No oil by ANY of the big Oil Manufacturers make an oil good for that loading - so you'll get WEAR with these cams.
There were a number of snake oil products that began to surface claiming massive film strength (over 200,000psi some of them) and gains in hp, better economy etc a few years ago (Bitron etc etc). They all had one thing in common - at least those that did actually work and several did work. That was they were chlorinated parafins.... which means in laymans terms that the oil with these additives had no additional alkaline reserves, and in fact over time, the acidity from combustion residue could actually climb to the point it would erode the engine.
A typcial TBN of 8 is a new oil... when it gets under 6, its time to change the oil... these snake oils would reduce wear but over time would reduce TBN to almost nothing... then you'd get acid erosion... that is why no oil company would touch them.
This scientist - which for commercial reasons must remain nameless - found a way to crack the molecular structure to create a high alkaline reserve AND enjoy high film strength. The result was an additive and or oil that trades under the name Oil Extreme. It has a TBN of 320 - which is about as far above the top oils like Mobil ONe as the star is from the sun. The big oil companies will catch up but may be a year or more away yet. Adding Oil Extreme additive to say Mobil One will provide a film strength around 270,000psi while increasing TBN from 8 to around 24 at recommmended dilution. That means that if you sent the used oil away after 5000 miles, it'd still be rated higher than brand new oil! It'd still have about TBN of 18 (compared to around 8 new).
so what does this all mean? It means that with a film strength of 270,000psi - greater than anything an internal combustion engine can produce - you can run a very thin oil for even more power and yet still reduce wear. It means also you will have more alkaline reserve in your oil from combusiton acids than any major oil on the market.
There is one other oil using the same product as Oil Extreme but secrecy between the two companies that the scientist made arrangements with meant I've never been able to find out who - it could be Royal Purple but because I do not know - I'd run Oil Extreme because I know it definitely has this technology. The scientist involved got ripped off by big oil and that is why he will not share the technology with them.
I've used Castrol 0W/30 with Oil Extreme on some hot engines very successfully. The 50 weight oils are the thick "syrips" that are required when you run aggressive cam ramps etc without Oil extreme in racing engines - its dinosaur oil!
We went from Quaker State 50 weight racing oil in the 2500hp blown alcohol pro-mod doorslammer to Oil Extreme. What difference did we see?
Quaker State oil would last about 3 runs before turning to milk (from methanol dilution) and we'd change it. The engine would typically require replacing at least a pushrod and / or valve spring or two every race day. By end of season the engine was stuffed and needed a complete rebuild. We'd go through heaps of pushrods and springs, on top of the normal stuff like blowing up the burst panel, breaking blower belts, smashing pistons and rods etc etc.
With Oil Extreme we went a whole season with NO BREAKAGES PERIOD except one! The engine guy forgot to pre-lube one pushrod and it got blued on top and needed replacing - as did the spring above it... that was it. No wear on any surface after a full racing season running between 2750 and 3000lbs to 6 second passes at over 200mph.
Oil changes? It'd last a whole day, not just 2-3 runs.
Go figure.
Top racing teams are using it now, some quietly, some openly. F1 in Europe were seriously interested (Jordan used it in F3) but the pull of the big oil companies was so strong, they risked losing major sponsorships to continue using it... that's the problem. You don't have to wait until they find out how to make it.. look at
www.oilextreme.com (if I recall) and get some... and no - I don't get paid for this and couldn't care less whether you use it or not... that's your choice. But its what I'd be doing and I guarantee I'd get my engine to run quicker and smoother than on any other oil you're using.
