Tell the history of the viscosity you have used.

[callbay]

Here is mine. In the 60's I used 10-30 dino a few years and then switched to 10-40 dino till about 73 when I switched to 10-50 dino. Then in about 88 I switched to 5-50 synthetic. After joining BITOG in 05 I switched to 5-30 synthetic and still use it unless I need to use 5-20 untill a warranty is up. I do use 5-40 synthetic HDMO in a 98 Jeep we have.


Hope we will not criticize but just report out histories.

Mine depends on the vehicle. 5-20 since new on the '06 Honda Odyssey, 10-30 in my '97 and 2000 Chevy trucks.

78 Mustang 2, the 4 cyclinder used so much oil that I never changed it, just added about 1 quart every 2 days. I was using the SAE 30 recycled oil at Dollar General. It was $0.50 a quart and I was mad when they raised the price to $0.75. I was in high school after all.

84 Subaru GL-10, great little car. Used either Havoline or Pennzoil SAE 30

After that, I bought my first new car and used what the owner's manual stated on all our cars since then (5W-20, 5W-30, and 10W-30). Just recently started running the 0W-30 and going to move the Honda over to the 0W-20 soon.

I have never myself used anything over a 30 weight in any of my own cars.
GC 0w30 is probably the thickest oil I've used.
Probably ranges from PP 5w30 to GC 0w30. and some 10w30's in between

 

[addyguy]

5W-30 in everything I have owned, with the odd fill of 10W-30 thrown in.

Callbay: What vehicles were your oil choices used in? Did you ever use that STP '15,000 mile' 10W-50?

 

[cp3]

Not much variety here. Since I've come here all I've bought is 5w30, recommended for all of my vehicles, untill this year as I now have 0w30 waiting for next changes. Other than that I may have used some 10w30 years ago but that would be it.

 

[williar]

10w30 or 10w40 in the 60s, 70s, & 80s. Maybe with a can of STP added to the oil burners. 5w30 in the 90s. GC 0w30 after 2001.

Droll, any chance you hung onto the shelby?

 

[daman]

Back in the day i used 10w40 or 20w50 ONLY i though anything "thinner" was no good and wouldn't protect.

 

[Johnny]

I could only wish I had. It was a graduation gift from my Dad and I was young and stupid and basically run it in to the ground. If I knew then what I know now, I would of put it in storage and paid for my retirement today. It was certainly a Corvette killer.

It was white with the twin blue stripes running down the middle.

 

[mac9128]

Thats awesome. I have a soft spot for mustangs especially shelbys. I'm sure you still had fun driving it into the ground. Anyway..back on topic

When I first started driving I had a Toyota 4x4 pick-up (1986) I used Valvoline All-Climate 20W/50 as that is also what we used in my folk's 1985 Mercedes-Benz 300D-T. We bought it by the case and always had it on hand. I was pretty loyal to Valvoline and even continued to use their 20W/50 in the white bottles after they stopped calling it "All-Climate." More recently I've been using Toyota 5W/30 in my wife's car (my car is a company lease any all service is provided). I bought my first BMW motorcycle (first an Oilhead and then two Hexhead boxers) in 2003 and have used M1 15W/50 in those ever since. OEM filters always.

Back when my folks had a 1978 Winnebago, we'd use non-detergent 30Wt. Valvoline in the motorhomes Dodge 440 V8. Why non-detergent? I dunno...guess my dad thought it was the stuff...
