Thanks, Michael. I had the feeling that this point -- today's oils be mo bettah that those of days of yore -- pretty much covers the matter. I do use Mobil 15W-50, like many here. I suppose that now that I are the proud new owner of an oil pressure gauge, I can use it to determine whether the oil is doing its work. That's kinda-sorta the bottom line, isn't it? That the oil pressure be not too high when things are cold, and not too low when it's bakey outside? -- RJS On 07/29/2011 01:56 PM, Michael Snow wrote: > On 7/29/11 4:44 PM, Rocket J Squirrel wrote: >> recommended oils >> chart in his 1984's owner's manual ("Lubricants," p. 54) and wondering >> what the right viscosity is for conditions where the nighttime lows are >> in the mid-40's (F) and the daytime highs are in the mid-90's. > > I think it is important to understand that the engine oils available > when the 1984 owner's manual was printed are very different from those > available today.
