[Healeys] Oil additives -- great informaton. Thanks.

Hello

How much is a US quart?

Is it a quarter of a US gallon which is 7/8ths of an imperial gallon which is equal to 4.54609 litres?

Wouldn’t it make sense if everyone was the same and that the US didn’t have its own weights and measures.

The best price I could find for Valvoline VR-1 20w50 on Wallmart's site was $7.03/quart & it was shipping from "Zoro", who ever that is. The next best price was $9.11/quart shipping from Speedway.

Walmart had no problem shipping me a crap-ton of Valvoline VR-1 20W-50; still don't understand why the outfit in the Midwest I bought from before refused to ship to me.  The Valvoline saga has some strange twists, a few years ago my favorite parts house 'had to pull it off the shelves;' I never got an explanation there, either.  I haven't seen it on any parts house shelves since, but as long as Wallymart will ship for free @ less than $4/qt I'll be happy.

Hi, 

Thanks all.  As is usual there is a lot of good discourse and experience shared by the list.  What triggered my question on oil and oil additives was the observation of a bottle of Red Line 10W40 image that did not display the usual statement that it contains ZDDP.  For decades I have used that oil as it carries proper oil pressure, suites the climate, etc.  However, if Red Line stopped including ZDDP, I would find another oil.  I also recalled that some time back, Bob Spidell having to find a new outlet for Valvoline 20W50 as it seemed that it no longer cleared some California rule changes.  I wondered it this happened to Red Line.

So, I sent off an inquiry to Red Line and not getting a rapid response sent one to our Healey group.  The Healey group was much faster to respond.  While most business are slowed down by COVID-19, a Red Line response did come.  The assurance is that Red Line Motor Oil 10W40 (SKU 11404) contains good ZDDP levels, plenty for an Austin Healey's flat tappet cam and lifters; 1225ppm zinc and more importantly 1375ppm phosphorus.

As to their break in additive, their Web site indicates that a half bottle is enough to add to a conventional oil.  It also has bit of sulfur, 16.6 grams.  I have to wonder if adding it to their 10W40 could result in too much.  I am just not inclined to experiment.

The 3000’s owner’s manual only mentions 30 weight oil, even for tropical heat.  However, the “Work shop Manual” (the Green Book) has a much more expansive table that promotes a lot of weights depending on the manufacturer.  The aspect that modern oils are a bit different than those available when the book came out adds a bit more uncertainty.  

I am confident using the 10W40.  I used 10W50 in my Triumph, but it was an air-cooled engine and was REAL hard to start in freezing weather.  There were also a lot of reputable recommendations that led me to Red Line’s 10W40.  The oil pressure is proper, so I don’t see an upside for me to use a heavier oil.

Many thanks to the folks who responded.  

Bill
