Some New (I think) Oil Info

[Richard D.]

In my opinion, there's not a better informed group of folks with knowledge about cars than on this site.

It would be my guess, that many (or most) of you like to look at information related to the care and maintenance of our cherished Corvettes (and our other vehicles as well). I believe this falls into that category.

For my purposes, I believe I have enough information to make educated decisions on what oil to use in my cars (thanks Duke, and to many others also on this site), but I thought I would pass this on for those of you with interest in this subject, as some of the information related to oil selection covered in this write up I have not seen before.

This individual appears to have some insight into motor oils. But, I cannot say for sure.

If you have already seen this, I would be interested in hearing your assessement of his write up and his explanations.

I do not recall anyone ever mentioning this link before here, so I am passing it on.

Regards,

Rich

My head hurts, reading his diatribe is like listening to a neurosurgeon talk about *****, you older NCRS members remember who I am referring to. I believe the surgeon that wrote that article got caught up in over analyzing obsolete information that related to those funny little cars of foreign persuasion.

Dick well said! This guy is over analizing the whole deal. In my opinion not worth reading! Tom

Sorry, I just can't make it past "Lesson 1". If those Ferrari guys find this stuff enlightening or even interesting, they must be dumber than a sack of hammers.

Re: Some New (I think) Oil Info

When he opened the article with Please forgive me if I get too wordy or even verbose at times I should have known to stop right there and then.

He went on to be way too wordy and excruciatingly verbose. 3 paragraphs and my head began to ache that was enough. He may have some good or insightful information in there but no one will ever find it amongst the BS.

Geez, this guy is a physician. He should stick to doctoring, but I hope he never works on me.

Most of what he talks about is viscosity - ad nauseum. He discusses API S-categories but completely ignores C-categories, so he missed one of the two critical engine oil selection criteria.

I hope my paper was a little more intelligible, and it boils down to two questions.

1. What viscosity is required based on the lowest anticipated cold start temperature?

2. What API service category has the best additive package for the design architecture of the engine?

Like so many who get into big engine oil discussions, he's a well meaning amateur who doesn't understand how/why industry comes up with various oil formulations in the form of API service categories, hasn't read basic documents like API 1509, and can't see the forest through the trees.

All you need to do is answer the above two questions. Your owners' manual has data/charts on the appropriate viscosity range, and using interpolation 15W-40 is okay down to about 10-15F, which is likely below the temperatures that we cold start our vintage cars. If you have to regularly do cold starts below 10-15F, use 5W-40. These are the two commonly available viscosities for C-category oil.

I don't think everyone needs to be a fluid mechanics expert to choose viscosity - just go by what the manufacturer's recommendation was when the car was built! That's what I do because I actually believe that they knew what they were doing 30-40 years ago.

Service category selection is a little more complicated, but if you read my paper, I believe you will have a clear understanding of why C-category oils are best for vintage engines and why SM is best for modern engines, but not for vintage engines.

He will analyze your illness until you finally die before he does anything

Re: Some New (I think) Oil Info

That is what I was going to say. By the time this guy get's done annalizing you would be dead and gone!

Re: Some New (I think) Oil Info

Seems the guy has quite a stable of cars with Ferrari, Lamborghini, and Maybach being mentioned in his 'thesis'.

Too long winded.................WOW.

Oh...Wait...Isn't that what happens anyway?

Darn near just did to my youngest sister, but that is another topic for another time and place.

All,
his opinions were debunked by the majority on that site a while ago.
