Oil velocity? I thought we were talking about oil viscosity? Blind leading the blind? Either way, there is no better than Mobil 1, 0w-40, for bang for the buck, buy the 4 or 5 gallon jug at Walmart for like 28 bucks. The lower the viscosity at ambient temp the better. Always do a 0w or a 5w, at most, even in Arizona. It will flow better and quicker at startup, whether it's 100 degrees outside or 20 degrees out. The lower the w number the less resistant the oil is to flow at ambient temp. |

That's just me mixing up words. I see you're also guilty of it.

in our newish Honda it is either Castrol synblend 0-30 or Mobil 1 0-30. I am about ready to start using Mobil 1 exclusively since I have no more free oil changes at the dealer. they tried to sell me a cabin air filter for $45, I picked one up for $8, take less than 5 minutes to install. the Matrix has been on a diet of Mobil 1 10-30 for a few years. the Altima has never seen a drop of that synthetic stuff I buy what ever is on sale including plenty of Super Tech 10-40, still runs great and sounds great with 200700 mile on the odo!

I was reading the original owner's manual earlier and it recommends a 3,000/3mo interval with a lot of short run about city trips so... hm. Maybe I will just go with MaxLife and a Gold filter. Before long road trips, Mobile 1 might do better. The bit about always using the same oil is most likely phooey. Probably marketing cooked up by a company to get people to never change from theirs once people started. |

We were. He was. Oil viscosity is simply a measurement of its' velocity... through a viscometer. Irony can be so ironic, don't you think? How oil flows at different temperatures isn't as simple as "this one is always thinner, that one is always thicker...etc.' Additives like pour point depressants cause oils to behave differently only at increasingly cold temperatures, resulting in higher or lower (before the) W numbers. That's why it's called the "W(inter)" number. but, it also has nothing to do with the oil's properties at higher temperatures. The number after the "W" is a measure of kinematic centistokes at exactly 100C/212F. So, 0W30 , 5W30 , and 10W30 all flow exactly the same at that higher temperature. 0W"x" doesn't automatically mean it's "thinner" than 5W"x", 10W"x", etc - it may simply have more (or better) pour point depressants or specific additive packages that allow it to maintain certain measured properties at colder temperatures. Depending on the formulation, a particular oil could be more resistant to flow at higher temperatures, yet have less resistance to flow at lower temperatures (e.g., 5W50 vs. 10W30). Simply using "ambient temperature" and "thinner" to define the behavior of a particular oil without reference to a particular temperature/temperature range won't work on that one!

I asked the guys who drove the airline shuttle busses in Astana, Kazakhstan one of the many days the temperature was -40 (C or F, take your pick) or colder how they get them started, or started without ruining the engines, since I never saw any pre-heaters or electric cords around their little enclosed lot. Seems they usually kept them running all day and all night when it got that cold, but not always. That might explain the loud knock in more than one of their vans...

Any recommendations for a 94' Metro with 120k on it...and I'm in Hawaii. Its hot and humid the guy I bought it from said he switched to synthetic 6 months ago Edited by slowjoe, Aug 20 2014, 12:23 AM.

5w30 (Geo's recommendation) or 10w30 (alternative) is fine year-round for you. If you aren't leaking or burning oil with non-high mileage synthetic, I'd stay with that. If you start to notice oil consumption, switch to a high mileage formula and see how it does. |

Here is what I read: "Blah Blah numbers. Something sciency viscosity. La la la blah, yada yada, yada yada. Read your oil cap. Blah blah. Don't maybe not yes do that. Hard" I've also seen some articles claiming that 10w-30 will never be truly as thick as 30w by itself at full operating temperature. |

Oil velocity definitely sounds pretty ummmmm, like you don't know what you're talking about. And it wasn't a one time typo. Mixing up the gallon and quart, okay whatever. I referenced solely the w number for a reason. At any ambient temp, the lower the w number, the less resistance to flow at that ambient temp. Of course, it is different than the viscosity of the oil at operating temp. I'm not sure I could ever think of a reason where it would be better to have a higher w number, anywhere. You? |

folks might want to take a gander over at bobistheoilguy.com to really be able to understand which aspects of the oil are most important to real application and which can be marketing hype or old wives tales. |

I knew what I was talking about. I just kept using the wrong word. Big deal. You're being REEEEEEEEALLY nit-picky if misusing one word is the only thing you can find wrong in allllllllllll the stuff i said in this thread. Edited by Cubey, Aug 20 2014, 01:24 PM.
