Dave, please change the file reference on Boule's spreadsheet in the Tech Section so folks don't have to go through this again.  

It isn't a zip file, it is a full folder full of stuff including Boule's two baseball practice schedules that he keeps.   AND 3 copies of the same .obd spreadsheet (Boule only used Open Office products back when he did this).

I have attached an .xls microsoft friendly version of the file to this post so you can lay hands upon it.

AHA !!!!    I see why boule renamed the file, our site text box won't take a spreadsheet format.

So it is attached as a fraudulent .zip file, just copy it to your desktop and rename it .xls

Examine away ..... you will find that standard Castrol GTX (all weights) is now a SN dino car oil, and specs exactly what the sorry Edge stuff did as it turns out it too is a standard SN car oil.

Nobody does VOAs on Castrol GTX as Castrol says up front what it is ..... a "sludge resistant" SN dino car oil.    

Art, you need to click on the links provided in these discussions and READ what they say.

Now, Stinger and his high mileage bike.    We have done this already, with both Stinger and WD.   Here is what we found last time around the Stinger/WD  barn.    

He used different brands of oils at different times.    Both like Harley weight oil because that is what they have always used.  Some of his oil changes (I guess you could say most of them) were done a long time ago --- back when all oils all had significant amounts of ZDDP in them.    Thus he got what everybody got back then, adequate ZDDP to keep his valve train happy.

Now he's not getting that, but since the name on the jug stayed the same he considers it all good to him.   I think he's in error about that lately, but it is his bike, now isn't it?

Next, Stinger has been around this barn before and isn't likely to want to go do it again.   He just tosses out a Billish sort of statement and leaves.

WD's Savage bikes have all died electrically and been replaced (except maybe one, the one up on the cinderblocks).

If you want to play Stinger for him, that's fine ---- but you are the one making big assumptions about an oil and a situation that you can't even put a bottle type and a weight to.    Castrol is just a brand name, one that has been moved around all over the place by British Petroleum, who owns it now.

And, having been around the Stinger barn before, I can say he's had his bike a while and puts a lot of miles on it and he changes his oil regularly.   Good for Stinger.   Most of his Castrol used in his bike was probably built by Castrol Company using domestic American crude oil as the base stock.

There is a wide range between optimum and adequate --- if you keep any sort of oil in your bike and change it normally, you will get normal performance and normal life.

Do you want your Savage to need a major rebuild around 60,000 miles?   I think most of us might could use some new rings about then, but replacing the cam and tappets doesn't have to be.   Good levels of ZDDP cuts down on ring and cylinder wear too, BTW.

Savage Rob and some of the old guys have had to rebuild their engines totally and replace their cams and tappets at normal mileages using normal car oils from back in the day -- we try to do better than that now days.


     

Boule's blend table is all numbers and no formulas. Here's a link to a formula:

File dropper permits you to share a file in its natural format --- let's see if it can handle Boule's baby.    You will have to pick the one you want and download it.

Yes, there are formulas behind the numbers, but the list won't let them show (doesn't handle the spreadsheet format at all).

Let's see if this one rings the bell.    

Guys, you are adding and subtracting and manipulating PPMs like they are an interchangeable concrete thing.    They are not.

PPM (parts per million) means a ratio of one item to another item divided by a million and you don't add ratios to another ratio and subtract them.    PPM is defined and always created by comparing the weights of the zinc (the heaviest part of ZDDP) to the carrier oil weight.

It isn't volume and it certainly isn't ratio vs ratio.

It is weight to weight, divided by 1,000,000.

Nobody said this was easy .......

You are right OF. I am just making the assumption that the weight of the oil in the red line solution and the weight of the rotella oil are close enough to make my calculation reasonably accurate.

Yep, what is reasonably accurate.

In case you are wondering, this is the 3rd weekend in a row that is has rained here and I am going nuts.

AND ..... while you are oggling them spreadsheets, oggle this a little bit.    

2013 was the time frame this comparison was done.   Gotta like that Delo 400 LE for its raw specs, but then got to toss it out because of the VERY High 117 ppm moly content.    

NAPA gets the next nod, for good specs and no moly.  

Next down the list is Walmart Supertech, which has a smidge of moly, but nothing like the Delo 400 LE has.  

Rotella T triple protect come next, but it is weak compared to the winners above it.
