Ooooh, a metal can.

Ooooh, a metal can.

Yep Dad used to buy them through the shop for Wholesale. Those were the days when oil was cheap.

Never bought ant strait weight

My HS auto shop teacher had his own ideas. Pz made sludge and the only oil worth having was Valvoline sae30. So I bought that.

For me it was Pennzoil SAE 30 for I believe dads old lawnmower. Lately, it was some Super Tech HD 30

Exxon … worked at an Exxon gas station when I was 16 …

I am sure this isn't actually the first straight weight oil I bought, but it's the first that I still have a clear memory of.....
Wolf's head 30 weight HD that carried a CD rating. Got it for my dad's boat that had a little diesel in it.

I am sure I must have picked up some straight 30 for my lawn mowers way before that but for some reason that memory sticks in my mind.

Back in the late 60's / early 70's I used straight 20W in the winter and straight 30 weight in the summer. This was in the Northeast at the time...Buffalo, NY.

Montgomery Ward house brand SAE 30 oil in the 1980's. I was too poor for anything else.

 

[Fattylocks]

Bought or swiped off the old man's shelf in the garage?
Either way to long ago to remember.

My first car in 1959 which was a 47 chevy, I used sae10 in the winter, 20 in the spring and fall, and 30 in the summer. Changed oil every 1000miles or sooner. No oil filter of course.

 

[Linctex]

Back in the 60's and early 70's, there was a ton of 30w used.

Our farm was 100% SAE 30W until about 1984 or 1985, I think.....
I was the first to purchase a 55 gallon drum of 15W-40.
My dad thought I bought the wrong stuff.

This was the first one for me. Supertech CF rated. I bought it as a super cheap flush oil, to drain and put a few litres back in, start it for a minute then drain again...when I wanted to leave the oil filter on one more run. It's also in my 83 Caprice right now, and it runs the same on it as it did 0w30 or 5w30. I haven't put many miles on it, because it's my winter beater, but I did tow 3 times this summer with that oil in it, no oil usage noticed so far. I ran it full throttle all the way up the hills.

The car is sold to my body guy as soon as I can pick up my truck with new cab corners and rocker panels. He's swapping an LS engine in, so I wasn't concerned about the 305 blowing up or having the best oil in it.

It was Quaker State SAE 30 API SF. It came in metal cans. A case of 24 cans could be had for $13 when on sale.

 

[Wheel366]

I bought 6 quarts of Amsoil ASE SAE 30 which is now called 10W-30 Synthetic Small Engine Oil for my lawn mower and snow blower. Still have a few lying around since neither take that much.

 

[Sleeve396]

For me it was Amalie straight 40w or Cam 2 40w if I found it, I remember the Amalie was 69 cents on sale! I fed this to my 68 ss396 Chevelle in Miami during 1972

Never used straight, if there is even a benefit to doing so?

Generally more shear stable especially when used in hot air cooled small engines, although you can find some synthetic 10w30s that have no VIIs that would technically qualify as a monograde but are old as 10w30 because most people use 10w30 these days where Straight 30 was called for..
