Probably not that great since it's made with lighter base stocks than a 10W-40 4T oil. But there is only one way to find out, try it and report back.

Interested in how you can work that one out CATERHAM...got a hints for dummies on how to work out which base-stock is lighter ?

I look at the PDS for either and get a different answer re basestock weight.

5W oils use lighter base stocks than 10W oils, plus the the 5W-50 has a 180 VI, a further indication that relatively light base stocks are used. Are you going to argue with that?

Yes, I am going to argue with that.

firstly, 5W requiring lighter basestocks than 10W is a myth perpetuated even on the 101 on the front page... You don't "start with a 5W, and make it act like a 40/50 at the top end.

VII work both ends of the spectrum, improving the cold perforamnce, AS WELL AS the top end.

Don't believe me, then believe AFTON...

http://www.aftonchemical.com/ProductDataSheets/Lubricant%20Components/HiTEC-5710_PDS.pdf

Check out the treat rates of the 150N oil.

At a treat rate of 10%, in what's basically an ISO32 mineral oil, the characteristics are in the ballpark of the M1 5W-50 (very close, with a mineral, VI 100 basestock).

Note how the pour point has dropped from -15 to -42 in that example.

Note, this was a mineral "5W-50", with an ISO32 basestock.

Another manufacturer of VIIs (these are solid, not pre-diluted)
http://www.functionalproducts.com/Catalogs/Solid_VII_Products.pdf

Lists the starting oil for their 10W-40 recipe (page 4) as also an ISO 32...

So it's entirely possible that a 10W-40 and a 5W-50 could have identical basestocks...your assertion that the 40 has to have heavier basestocks because it's a 10W is not true.

As to why I called you out in the first place, looking at the PDS' for either oil
http://www.mobil.com/Australia-English/Lubes/PDS/GLXXENPVLMOMobil1_Racing_4T.aspx
http://www.mobil.com/USA-English/Lubes/PDS/GLXXENPVLMOMobil1_5W-50.aspx

shows the 10W-40 has a flash point of 212C, while the 5W-50 has 231C...logically, the 5W-50 is made of "heavier" stuff than the 10W-40, most likely base-stocks, as the VII additives tend to be somewhat lower in FP.

Yes it's made and bottled in US quarts in the States but distribution is limited.

I got like 10 quarts in my yard sale oil score a few years ago. I tried it in my Harley. Didn't like it.
In hindsight I should have saved it.

That makes no sense.
How does draining oil that is still serviceable,and replacing it with oil that is serviceable cheap insurance. If the oil isn't depleted then its performing the same as new oil.
Actually since engine oil requires some oxidation to perform as intended the old oil is providing better protection.

Wanna try that voila again?

Looking at the math, what I saved on oil and filters in the taxis by doubling the OCI and sticking to conventional was significant. Going to manufacturers recommended OCIs and synthetics for "cheap insurance" would have bought each taxi a brand new crate engine at the end of their service life, which wasn't needed anyhow since the engines ran fine while everything else was falling apart.

For the M1 5W-50??

If so, then they are giving it away considering the normal Ozzie prices!!

Yep, half price on 5W-30, 0W-40, and 5W-50.

last 5L bottle of M1 in my store, so word is out.

Bought some shell helix for less than $3/l the other day.

Something's moving

Sounds more like expensive insurance considering if the tbn is at 7 and starts at 9 or 10 you've effectively thrown money out the window.
Cheap insurance,right,because the oil is some kind of risk.


Simple. Rather than spending $35 on a UOA+TBN, I spend $40 and put fresh oil in. I periodically send samples to make sure wear metals are in order, but not every OCI. If, as you suggest, I were using UOA+TBN to make sure I was getting every last ounce of life out of the oil, I'd be spending hundreds in oil analyses before finally changing the oil.

My engine spends about 25% of it's total miles at Mid Ohio Sports Car Course or Watkins Glen. Under those conditions, I'd rather have the piece of mind of KNOWING my oil is fresh, instead of wondering if the next sample is going to come back with TBN of 0.9 or KV@100C of 11.0 and wear metals through the roof. So to me, the $5 difference between sending in a sample or just changing the oil is cheap insurance.

Nevermind that Porsche re-manufactured engine is $13,000 + 30hrs labor.
