A church key worked better than either of the above.
Full sized hole you'd pour oil out of and smaller hole 180 degrees away to allow air in and reduce the glug factor.
You had to be careful with the later fiber cans, since they wouldn't take too much downward force from either the classic piercing oil spout or a screwdriver.

One of the first synthetics I ever used in my 91 CRX was Pennzoil Pennzane 5W50. It's thicker, therefore it must be better...

Funny. I worked in the Space Program for almost 20 years and I use Mobil 1.

Good stuff, since I am now driving a 1980s turbo car.

The elves might have heard that. Be more circumspect, please.

Can't recall who said the original M1 in Oz was 5W. Maybe they will read this thread and 'fess up.

Thinking back, that TXT was before Group III synthetics, so probably PAO based and I suspect low in VII given it's shear stability. I would love to see a old spec sheet for it to see what it's KV100 and CCS was.

Ok, what would you use on a 1980s turbo engine with air to air intercooler. A grp III GTL 5W40 or a GRP II SAE 30 , given ambient temps not lower than 24 C.

Which 1980s turbo engine ?

Knew a few people who had turbos in the '80s, and lots of turbo bearing failures from the oils in the day, being non water cooled and all.

Vanellus C3 was one of their diesel oils.

Gr III was around, just we hadn't started calling them "synthetics" yet

Here's one of them, Shell's XHVI, from another book (pic harvested back off photobucket will try for a better version next few days)

It was Shell's 15W30 VII free oil.

Oz didn't adapt well to the 30, anecdotally wasting a few engines in a country where anything that consumed 1L/5,000km was largely considered time for a rebuild, at least of the top end.

Shell went to "XMO-Hi", 40 grade and the red bottles of DJR's Sierra

The TXT was called "Synthetic Technology", what would that have meant back then?

BTW I don't recall ever seeing that Castrol FMX back then.

 

[Shannow]

I think that was the start of the slide in the use of the term.

like méthode champenoise

Me ? Back then?
Castrol Edge 10W60, but it may have had another name like Castrol RS or TWS

This is the only piece of oil marketing that ever had much of an impact on me. Don't even know if this is true of Mobil 1 any more.

That was probably the most effective ad Mobil ever ran. I remember it, and in the ad the "295 degrees centigrade" was "563 fahrenheit" in U.S. versions of that commercial, units of temperature Americans understand.
They must be talking about the cylinder walls, since turbo bearings can get to about 450 deg F.
People just want their oil to not turn black and get scorched (oxidation), so it was effective as an ad to show the benefits simply.

 

[trooplewis]

Engine oils of the 80's?

Does anyone remember Torco Motor Oil?

 

[Yah-Tah-Hey]

I recall I was using Pennzoil Turbo Pennzoil 5w30 in the eighties.

Laugh - méthode champenoise - I haven't heard that term in years. Back when creme sherry was somehow cool and came in flagons.

Yeah I recall the TXT was sometimes referred as type of semi-synthetic or something like that, which is maybe what they were calling Group III back then. Rather than the blends we use today.

Which brings me back to Nulon or Penrite Full Synthetic 10W40, as both are full Group III 10W-40's with A3/B4. I've been tempted to give one a run, for old times sake.

Those metal cans bring back some memories!
