The now-defunct Mobil DriveClean Plus High Mileage 10w40 synthetic blend used to make both me and my car's engine very happy.
It was a ~$2/qt. bargain for its formulation (IIRC, it seemed to be mostly a decent G-III blended with >=~20% PAO?), kept my seals tight as a drum with negligible consumption (amazing for an old FIAT engine nearly as old as me with 124k on the odo!), and kept the DOHC valvetrain quiet and the engine itself running smoooooth throughout the rev range. Of course, almost as soon as I'd discovered it, Mobil stopped making it.
Last two OCIs, I decided to see what all the Chevron Supreme dino fans were hyped up about (being strapped while Checker had a sale+rebates for 49c/qt. helped
), but one OCI with Chevron 20w50 and another with 10w40 have me fed up with all the valvetrain chatter and yearning for the glory days of that smoooooth, quiet, quality, bargain of MDC+ HM 10w40.
Now that all local remaining supplies of my beloved MDC+ HM 10w40 have been depleted, what would y'all suggest I look into next as a replacement comparable in quality, price, and other characteristics? Is Mobil Clean High Mileage 10w40 the "new version" just rebranded with the new Clean family name, or completely different? Would a Delvac 15w40 or other HDEO be worth a shot? Is any Maxlife Synthetic viscosity thick enough to be "like" a good 10w40 (I've read their 10w30 runs thickish)? FIAT twincams are known to have loose clearances and thrive with thicker oils, plus I live in Tucson, so I'll have none of your 5w-this or 0W-that, thx
(and I'm still somewhat strapped so nothing in the M1/RL/RP echelon for me, either
).
FWIW, my daily-driver is a '79 Lancia Beta Zagato spyder, which has basically the same engine as a FIAT 124/2000 Spider -- a DOHC, 8-valve 4-banger with timing-belt driven cams acting directly on inverted-bucket tappets (ahead of its time, no?
).
