OK, I'll confess to at least being curious about this stuff. And for what it's worth, I had seen the site several years before I discovered BITOG! At least he seems to have gotten rid of that seriously goofy synthetic music that used to bedevil the site.

Anyway, for me, this product is a brilliant example of the limits on "informal science." Bottom line for me is that while I'm curious, I'm not willing to put my vehicle on the line to test it, when I know that the more traditional approach works, AND I simply could not afford to deal with the consequences were I to find the product's limits and lose and engine as a result.
 
The guy should get some credit for writing the article. He tried to write it in simple form (if that's possible) so it could be easily understood. As with all articles...someone will find fault with it and it probably should be revised and updated to make it more easily understood.

Keep in mind he's a smart guy but he's a surgeon. IMO he goes too far the other way. His views on HTHS not being important are just wrong. Some of it I agree with but there are many parts that show he has no actual experience with engine building.

Blanket statement.

I run a 50wt and pressure and flow are pretty much instant. Where's the startup wear?

I don't suggest running it in a car spec'd for 0w-20 but a 50wt will not automatically cause more startup wear under the right conditions.

+1

But who really needs a 50wt oil for daily driving conditions? So, this discussion is sorta nonsense because no one with a modern engine really needs to use a 50wt oil to protect against wear.

Can you provide some links to these articles?
 
AEHaas articles make perfect sense and are very enlightening. If you assume 10w30 motor oil is much thinner than 75w-90 gear oil, you need to learn more about viscosity and temperature. The numbers are relative to temperature. At start up, the lowest viscosity possible is best. Any viscosity higher will cause wear at start up. At running temperature, lower viscosity will flow better and carry heat away. Just need enough viscosity to keep metal to metal wear from occurring.

I agree, there are only a few modern cars that could benefit from a 50wt. Some of the blown modulars come to mind. But for the average daily driven Honda it would make no sense. On the flip side, I get crucified for running a "gasp" 5w30 in my TL in this hot climate with people calling it molassis which is nothing short of retarded.

Ahhh, BGN, another opportunity to cross swords! Seriously though, I have enjoyed and respected your contributions here since you joined our strange little group. You do, however, seem to have a regrettable tendency to use subjective terms to spin certain points (but of course, not bearings, we hope...). That said, you do it with notable skill (keep in mind, this is coming from none other than a dreaded "trial lawyer"!). Case in point: I don't think you've been "crucified" for using 5w30 in your TL. And the "molasses" thing -- come now, we all know most of them are nearly as watery-when-hot as are many 5w-20s. Various participants have pointed out that you're one grade above where Hondacura says you should be. Nobody with any sense thinks your engine is about to blow up on you, but the fact remains, it is a valid point. And I do think we can all agree that a full decade into the xw-20 "experiment," we're still not seeing the junkyards filling up with 20-wt-destroyed Fords and Hondas.

Well, I'll just stop now. I'm a tad OT, and it being Saturday night, my BAC is such that my blood's viscosity has probably thinned down a grade or two. . .

It's good to be able to cross swords again lol. There have been comments in the past about me running molassis in the TL and even comments when I found what looked like metal in the oil was caused from my "thick" oil. It's all entertainment though. Have a good one.

I personally have VCM on my V6 so it cuts out 2 or 3 cylinders at a time depending on engine load, so ive been told that anything other than a 20wt won't properly lubricate the upper end. Therefore, 5w50, not so much.


Does this stuff ever stop?????? He's a surgeon. He makes some good points but fails miserably at others.

You can use a 40wt and your VCM will work fine.

Think about it for a second. If only a 20wt will work, what happens to those in Canada and cold climates where that 20wt is at nearly 40wt viscosity at operating temp. Canadian cars would not work....ever.

Think about this, it takes 20 minutes for oil to hit full temp and to thin out into the 20wt range. Does your VCM take 20 minutes to start working?

I was told my vtec wouldn't work with a 30wt. I've floored it 2 minutes after a cold start on a straight 30wt and it worked just fine. The oil was probably somewhere around a 70wt or higher.
 
Yeah, the most it should mean is a time variance until it functions. After the first few minutes a heavier weight should fall into the "range" of functionality. Imagine how many VVT sales would make it passed the EPA in the CAFE cycle if they couldn't work during the entire testing sequence.
