[Healeys] Shell Rotella T vs. VR1

Shell Rotella T is a line of heavy duty engine lubrication products produced by Royal Dutch Shell. The line includes engine oils, gear oils and coolants. The oil carries both the American Petroleum Institute (API) diesel "C" rating as well as the API gasoline engine "S" rating. Ratings differ based on the oil. Rotella oils like T3 15w-40 meets both the API CJ-4 and SM specifications, and may be used in both gasoline and diesel engines. However, it is formulated specifically for vehicles without catalytic converters, containing phosphorus levels beyond the 600-800ppm range.[1] Therefore, Rotella is not recommended for gasoline vehicles with catalytic converters due to the higher risk of damaging these emission controls.[2] Newer formulations of Rotella T6 however are API SM rated as safe for pre-2011 gasoline vehicles.

Shell is marketing their new CJ-4/SM oil as "Triple Protection," meaning it provides enhanced qualities for engine wear, soot control and engine cleanliness. Shell's Rotella website indicates that on-road testing confirms the new Triple Protection technology produces better anti-wear characteristics than their existing CI-4+ rated Rotella oil. This is achieved despite a lower zinc and phosphorus additive level as called for by the API CJ-4 specification. (The 15W-40 Rotella T with Triple Protection oil has approximately 1200 ppm of zinc and 1100 ppm phosphorus at the time of manufacture.)

, though marketed as an engine oil for diesel trucks, Rotella T6 5w-40 synthetic oil has also found popularity with drivers and tuners of gasoline powered vehicles that utilize turbocharging or other forms of forced induction. Several owners of high performance model cars have adopted its use due to its high heat tolerance and its resistance to shearing. Rotella T6 is a Non Energy Conserving Oil, and does not meet GF-5 Oil specifications. When Rotella T6 was revised for the API specification(for use in spark ignition engines), its Zinc levels were effectively reduced. Higher(content) Zinc Additives(ZDDP) are required for flat tappet engines and cartridge bearings, which In previous formulations Rotella T6 had desirable levels of Zinc(ZDDP)

I guess it is saying we have to use a bit of additive to T6 to bring it up to 1500 ppm? Or, the Triple Protection Technology gives us the same anti-wear characteristics?

talked to them today--VR1 20w-50 has 1400PPM zinc.

IIRC a couple of years ago diesel oils also went the reduced zinc route.  You can check zinc levels online from the oil's website - usually by downloading a pdf.
What I settled on doing for our beloved '69 Ghia convertible and her Healey consort (once I get him going, that is) is a zinc additive. My understanding is too much zinc can also be a problem, so adjust the additive to the underlying zinc in the oil you are using (you want about 1500ppm total).
Alternately, some folks might smuggle in VR-1.

I've used this for years with satisfactory results, and was looking to re-up my stash, but my usual source, RuralKing is now refusing to ship to California (their cust. serv. wouldn't say why, but they're a guns and ammo dealer and might be making a political statement as apparently no other states are being boycotted).  Anyways, I found it at Walmart and they had a '2-pack' for $8.76 ($4.38/qt), which is about as good a price as you can get--'regular' price is over $7/qt--plus free shipping.  I thought this might be a goof on their website, but I took a chance and ordered; and the email confirmation showed 24@$4.38 ea.  Maybe they'll claim a screw-up, and try not to honor the order, but I thought I'd pass this 'deal' along:
