Logic says that if the oil is so slippery, it is not allowing the metal pieces to touch,and the roller does not "roll". If they are not touching, because of the oil-film, what is causing the wear? Certainly not friction. What protected the other rollers? Was there only enough zinc in the oil at...

Congratulations on starting your new Bike club. Being on a bicycle is the true essence of freedom. I have a bunch of bikes for road and offroad. I sponsor the LSU tiger Cycling Foundation. They just won the Louisiana and Mississippi Bicycle Racing *** . championships. Our bikes include 2 ea...

For every day consumption Community Coffee medium is hard to beat. I also love Major Dickason, from San Francisco. Lance Armstrong raves about it and takes it with hikm whenebver he is abroad. I give it to my good customers.

My company sponsors a local cycling team, and have changed them to Purple Extreme. It works very well as long as the chain has been cleaned well, prior to application. We have people using it in Adventure races,triathlons,MTB and road. The consensus is that it stays on, and lubricates here in...

I am amazed that all of a sudden RP OTC are giving problems. I have used them fo 14 years on an extended basis. I run 15,000 miles with a filter change at 5000 miles. My numbers have always been good. On this forum the only problem I have seen is with the oil losing a little vis, normally thru...

You got it, Unless of course you use stainless on stainless...... Llew

The torque setting is based on dry threads. Coefficient of friction of .2. Find out the Coeficient of friction of the anti seize, compare it to .2 and adjust the torque by that amount. Example. Dry stud B.8 100 ft/lbs. .2 friction Anti Seize Coefficient of friction at .1 .1 divided by 2= 1/2 X...

We use PAO base oils, an API additive pack from one of the mainstream suppliers, with some carrier oil to put it into solution, and our additive, Synerlec.

If one reads the specs published by State of NC it says Synthetic Lubricants, Group 111 allowed. To say that RP is a group 111 is disingenuous.If that is true, only Chevron has a true synthetic.

Will find out Monday Llew

This is truly amazing. Your car seems to like the RP stuff, but you read somewhere that the RP was garbage, so you are scared stiff. This board is about proof, not gossip. People have been enraged because the oil dropped in viscocity, yet the RP has one of the best figures when it comes to...

I resemble that.

Hi, The 2 oils will mix without any problem. I have run 5W-30 in my wifes Suburban for 16000 miles. The oil has spent a little time in the lower vis area and then come back to a 5W-30 at about 4000 miles. But, my wear particles were always low. I do not have a problem with the oil thinning, as...

Hi Quick-16. My point is that when you run a VOA it is ONLY for use against future UOA's of that product, same batch, and formulation. Save some and send it in when you send the UOA, for the lab to use as a reference. Then compare the UOA's to the reference (VOA). We are not in the habit of...

I really could not tell you. I have no idea why the bearings were pitted and scored. Do you have any analysis to show us when it occurred. There are so many things that could have gone wrong. Assembly, tolerances, silicon in oil, particilate in oil passages after assembly, starting up dry, no...

The Rp 5W-20 is a Synthetic, with some mineral oil in the Additive package. The proof of how good the oil is, is in it's life in your vehicle, under your conditions. Send some of the oil for a UOA and then trend it from there on. I am always available for RP help. Llew

I have always understood that a multigrade oil flows like a light weight and protects like a heavy weight. Sounds like Muhamed Ali. Racers want the lowest weight oil for horsepower, with the highest amount of protection. So it is a balancing act that they play to find the perfect #. Shell has a...

Dock Holliday, I have been trying to work out a reply. You have answered your own question. Single grades are just that.It is all temperature related. A single grade oil with a steeper VI, than the multi-grade oils. No VI improvers are added to make the single grades.Some Synthetic base oils...

The abuse of the prisoners has given the war detractors a bone to chew on. Let's face it it was deplorable and very stupid. Look at the idiots in the pictures. But why are we,(USA) trying to destroy our country because of it. War is **** . I bet a whole bunch of dead guys would be only too happy...
