All Red Line Race oils are full of moly. I run it as a blend in most of my vehicles and YES I do see a better fuel economy in older vehicles.

If there is something wrong with my engine as we speak then I have no idea what it is since there is no symptom that I can hear, see, or feel. I should have a 35K UOA sometime in May 2014. Stay tuned.


Nice, I look forward to seeing it. I love these ALH motors and what they can do. I really like my CR TDI but as far as pushing the limits of efficiency , it seems like ALH is the way to go.

Can someone please tell me what is SAE 0W-5?

Last time I checked SAE J300, there are:

0W
5W
10W
15W
20W
25W
20
30
40
50
60

..and with the latest addition of SAE 16.

Your chart is incomplete.
You can have 0W-XX, 5W-XX through 25W-XX, with XX ranging from 16 to 60. These are the multi-grades.

There are single grade 5wt and 10wt oils. 5wt oils are supposed to have a KV100 in the 3.8-4.09cSt range. So while while there is no official SAE 0W-5 multi-grade oil, race oil formulators use the designation.
Of course as was discussed early in this thread, the NEO 0W-5 is way heavier than that and really is a 20wt oil. So assuming it does have the properties of a 0W-XX oil it really should be thought of as a 0W-20 if it's HTHSV is at least 2.6cP or a 0W-16 if it's HTHSV is less than 2.6cP.

Just an update on this oil. I am at 28K miles going to a 35K OCI on this same oil and the mileage is getting better than ever. I replaced the original glow plug after 300K miles and mileage is now close to 65mpg on the last four tanks. A 35K UOA will be available some time in April. As of today, the car has over 303K miles and still run better than new.

Thank you for the data and being a test mule to experiment with thinner oil. I'm trying 0W-20 in my old 350 vette.

I understand your frustration in that you know what you're doing and sharing info, not a beginner begging for help. There are so many eager beavers that jump in and tell you how you're doing it all wrong, and have chips on their shoulder about which additives are socially acceptable here. Some must believe a large post count is a substitute for an engineering degree or experience in the lubrication field.

I get it. I understand that you are more concerned about the viscosity of the oil rather than the chemical additive properties so you don't care about mixing brands to bring the viscosity down during the OCI.
