There is a lot of interesting work going into the nano-additives realm. I don't have access to the full paper -- but I'd be curious to see what size these particles are and if they are affected by some of the filtration methods utilized in the field....

Graphene is simply a single layer of graphite. Graphite is a great lube because the vanderwalls bonds slip easily when a shear is acted on it. Graphene is extremely strong because you're applying stress directly to the ionic/covalent bonds that make up the crystal structure. Carbon...

Originally Posted By: Rick in PA I believe it. I use to change my oil on an asphalt driveway under a carport, same place every time. Now and then, I'd spill a little oil, but I'd mop it up right away. After years, the asphalt in that spot broke down and became more like gravel. (I've since...

tl;dr It's well known EGRs lower fuel efficiency. You're wasting space that could be filled with a fresh air/fuel mixture with exhaust gases. The benefits of EGRs can be heavily debated from both a lab stand perspective as well as real world operation. I, personally, hate them and remove...

Most DI gasoline engines are also turbocharged. Did they compare this as well to non DI engines? Turbocharged engines will have vastly different fuel delivery profiles - which could cause the soot. I know my turbo DI car spits out a little black cloud of soot every time it's hammered because of...

I'd be really curious to see how this relates to a similar system with lower temperatures - read: a reciprocating piston compressor. Does that mean that you could be seeing 0,05mL/min heading into your compressed gas stream? Would modification of the ring pack and positioning possible minimize this?

Shannow - your posts intrigue me. You must be a mechanical engineer doing design work, eh? a 12,000hp fan sounds like something that'd be used in a wind tunnel. Especially if you're trying to figure out how to manipulate the airflow mechanics...

I've seen fallout happen too if the lube wasn't heated hot enough when blending - the solid additives didn't fully dissolve. MolaKule - Make a quick blend w/ a clear base and some antioxidant, put it in a clear container, then put it in a sunny window.

Old pool table lights make great shop lights as well. Plus a lot of them take standard bulbs instead of tubes so getting LED retrofit is significantly easier. I'm a big believer of LED. Lower power consumption and crazy long bulb life. The downside is you gotta pay up front - but at the end of...

Yeah a vibrating/reciprocating tool won't cut well on the hardened steel nails as others have said. You need something that's spinning so the heat it generates can help soften the metal a bit. Never hurts to have a good angle grinder - they have a lot of good uses. Plus - if you don't have a...

I could only see the cleaning chemicals contaminating the oil if they were spilled onto the bottles - or slowly dripping - and not cleaned up.

Sounds like you got some really old fluid that's been degrading. Time for a flush and change. Here's a great little article on oil breakdown that's nicely simplified. http://www.machinerylubrication.com/Read/475/oil-breakdown

I'd run Rotella T6. The 5W40 will give you the cold start pumpability but will have a thicker oil film on the higher end. Portable engines typically don't have the tightest tolerances and wear pretty weirdly sometimes. The 40wt is just 1 step higher, but can greatly increase the oil wedge's load...

Iso-680 or ISO-460 (hot or cold climate respectively) NON-EP gear fluid will work perfectly. You can find it everything. I prefer to support smaller suppliers/blenders - but you could just as easily purchase it from one of the big buys like Mobil or Shell...

Yeah NEVER stop after a hard brake on new pads. It will deposit the pad material unevenly and essentially messes up all the work you did bedding them in. Hard, but not ABS-inducing hard, brakes down to a slow roll, then plenty of drive time in-between to cool the brakes down. As for the...
