Your reports have been a model of consistency, Mscales. They've all been beautiful. The numbers are all the more impressive with the big displacement/sump size ratio, and longer valvetrain. The only thing I would recommend is stretching the interval out more. There's no reason why you couldn't go 5000 miles on this oil.

Buster you have been paying attention to my reads for you !!!


Yes, I have. I try and learn a few things here and there as long as it gets through my thick head.

This V-10 is clearly designed to provide good oil pressure with a 5w-20, hence the bearing wear is low. I suspect it also has roller type valve lifters to eliminate sliding friction between the cam lobes and lifter bodies.

Generally speaking, the 5w-20 oils that pass the Ford/Honda specs use a higher quality basestock than most of the 5w-30 petroleum oils. As has been mentioned, they have to pass a 160 hour, double length Sequence IIIF test. This is a high temp/high load test in the 3.8L, GM V-6 engine to evaluate wear/deposits/oil thickening.

True, true true, but we are also seeing 20wts excell in 4cyl and 6cyl as well. I really do think its the quality as TS mentioned and the Flow factor. I think RL builds a awesome 5w-20.
 
Say, my wife's 2002 Honda Accord V6 started getting Mobil-1 (presumably 5W-30) at 3500 miles.

Is there any reasons to think that she could be using a better oil in the 5W-20 range? I much prefer synthetics, and use both Mobil-1, Delvac-1, and Amsoil products in a variety of applications.
 
Hey there,

I will admit I am new this OIL THING. Before
anyone starts praising anything look at where the
vehicle and oil came from. That's like saying
you were amazed when the creator of an invention
made an improvement on it. Who better to know
this stuff then Ford on THEIR vehicles.

If anything else I would say we should EXPECT
these kind of results considering it's their product. I say put this stuff in a Chevy and see
what happens. Then we will be getting somewhere.
BTW- I drive FORD.

I dunno, joee. When the 5W-20s hit, the prevailing view around here initially was, "not in my engine!". But several people pointed out that Ford and Honda's metellurgy and clearances hadn't changed. The 5W-20s seem to be holding up and engines aren't tanking. Yeah, the original intent was to boost CAFE numbers a smidgeon, but the engineers and blenders seem to have thought this all out. (Amazing...) I'm tempted to try an interval of 5W-20 in my Hyundai V-6 at my next oil change just to see. I purposely broke the Korean in on 5W-30 (Hyundai recommends 10W-30, 10W-40, or 10W-50 for year 'round use above -10 F. and it NEVER gets below +30 F. where I live.) after the first 600 miles and saw no observable oil use, so I suspect one of these "super" 5W-20s wouldn't be catastrophic either. Funny thing is that the Korean has just as tight bearing and cylinder-piston clearances as Honda's and in some instances, tighter. "Flow, flow, flow" says it all...

As an aside, I took Patman to task for, what I thought at the time, "recklessly" suggesting 5W-20 for folks in cold climates instead of the usually recommended 5W-30 oils. In hindsight, I believe Patman was on to something. I've seen the light!

LOL...shall we start digging up some Mobil 1 reports?

Seriously, I don't think the Fe is out of range for that engine. My F150 4.6 ltr had an Fe of 11 at 4500 miles OCI with Chevron Sup 5w-30 but with 10,000 miles more on the engine. Also, my F150 wasn't used anywhere near as hard as this v10 was. Blackstone shows a universal average of 22 for Fe on my F150 report.
