One more thing: Even IF 5W-10 or 10W-30 oil is visually "thicker" when at... let's say zero degrees F... that doesn't actually count for anything. What counts is how much energy it takes to move it and move things within it. Even if you stick it in the freezer for a a couple days and you find it's thicker than when it's a 100 degrees, that makes nothing without a real laboratory test conducted by the oil company. Your engine has up to so much energy at it's disposal in the starting process to pump that oil. They don't just go by "it's thicker when cold!". The labeling of it's "weight" goes by how much energy it takes to pump it/move it when mixed within gears and such. If your motor oil is causing clogs/oil starvation when cold starting, you have something bad wrong way beyond your choice in 10W-30 or 5W-30 unless, as I said many times, you're in the arctic region. And like I also said before, your Metro's ~4qt 50/50 antifreeze mix will begin to freeze at minus 34 degrees F which is only 4 degrees below what 5W-30 is rated down to. Ok, I'm done now. |

Well, I know from watching that warmed up 5W30 comes out of the pan like it had 0 viscosity. At 5:30 the experiments begin.... 5W30 vs. SAE 30. |

Based off of what I've read from the experts, I still respectfully disagree. Everything I've seen shows that a lower 'W' number will for easier at any ambient temp. Sorry, I'm out as well. |

Completely wrong.0W-30. 5W-30 and 10W-30 act differently at anything below 100° or so. That's the whole point. |

I guess I must be missing something here. My FSM plainly states to use 5w 30 oil. On my oil cap it plainly says 5w 30 oil. No reason for me to read thru 7 pages of personal " I'm right, your wrong neener, neener, neener"............

The owner's manual (not FSM) says 5w-30 recommended, 10w-30 usable, 0W-30 if nothing else is available. It makes sense it would say that since normally anyone reading the FSM who it was printed for, professional mechanics, would have access to any oil type they wanted. Meanwhile, end users (the car owner) might live in Ratsass, Alabama where the local store only carries 10W-30 and it's 50 miles to the nearest store that carries 5W-30, so he uses that since the manual says you can. |

Excuse me? On what part? Page 195 from my original 1993 Geo Metro owner's manual (click to view full size): ![]() EDIT: A thought occurred to me.. is 0W-30 NOT the same as SAE 30? Normal logic leads you down that road of thought.. if it's 0 it would be "30". The world likes to change terms all the time on crap, after all. I guess that is where my "ignorance" lies? EDIT 2: The chart actually shows 10W-30 stopping at ZERO degrees F, not minus 20 like info I found online says. Hey, I'm going by what the company who put out these cars said back when they were new.

Well, they also said that 10W-40 was okay. Then they later determined that it was contributing to the burned valves problem and should never be used. |

I was just using Alabama as a random example of a state with a lot of rural towns that might not have a store carrying every oil weight out there.

"They" who? The 93 owner's manual says in bold letters not to use 10w-40. |
