The first HDEO engine oil you bought?

When I had a 1985 Mercedes with the om617aTD 5 banger turbo diesel, I bought 2 gallons of warren 15w40 and a STP oil filter at autozone. I think the oil was called lubriguard.
 
Delo 400 SAE 30 from the AZ closeout of way back when, gallons & gallons of it, none for more than 99 cents/gallon, a couple for ONE CENT a gallon! Way back in 2004, it was BITOG that turned me on to it, used the last gallon about 2 years ago.
 
Shell Rotella Synthetic T 5W40 CF-4. Back before the T1, T3, T4, T5, T6 lineup. Late 90's but may have been 2000.
 
Rotella T 15/40. It was what my dad ran in his OTR big rigs and so that’s what I ran in my 6.2l and 7.3l diesels. Still using it in my ‘02 Powerstroke, 2 tractors and ‘51 CJ3A.
 
QS 15w40 in use in the Ford 2.0 OHC gas engine several years ago. I remember the engine was very quiet on this oil. Can't remember the exact spec on this QS oil but it was a HDEO oil.

Shell Rimula R6 M 10w40


that was for a Fiat diesel, that I miss so much.


Then Rotella T6 0W40...to use in various gas engines. Currently using what I believe is the John Deere version of the T6 in my Mazda, good winter starts here in Canada.
