Mobil 1 0w20 or TGMO 0w20?

Then I must ask--what is the point? This suggests that any oil is too thick at start-up so the miniscule differences between any of them become immeasurable and irrelevant. I know that we love splitting hairs on the site, but sometimes it seems pointless to do so--particularly in this instance where any oil would suffice.

Just my

But really isn't the majority of what we discuss pointless? Why should VI be any different? As for the cold starts....I wish I could say I don't see a difference at -20C but the fact is I do and have in most of the vehicles I've owned.

Indeed it is and we worry about so many things that are pointless in the attempt to eek out "something" (of what we speak we know not, but we still want it). I fully agree that minus something temperatures can and do impact cold starts, but for the OP to believe that is true in FL and that 0W-20 is required is a fools errand. My climate is nearly identical to his and Mobil Super 5000 5w20 in my Explorer made no more start-up noise than my FX4 did with 0W-20 and am fairly certain over the last two weeks it has been just as cold (if not colder) in TX than it has been in FL. To each his own, but facts are facts...

If it adds anything to this thread, I took a bottle of Mobil 1 0W40 and Mobil 1 0W20 that I've got sitting in the shed when the outside temperatures were below -20 C (very cold), and shook them around out of interest... Both were very fluid-like and splashed around like water. Nothing out of the ordinary. Either of them would easily pump.

My car makes no funny noises whatsoever in the cold weather (and I'm talking real cold - I've started it down to -25 C). Yes, of course it cranks more slowly. Any battery cannot provide the same amount of current at low temperatures that it can at higher temperatures, and it's also slightly harder for the starter to turn the engine over. But it still starts right up, without any clicking, clacking, or noises whatsoever.

Some cars do make a bit of noise, but rest assured, from people that live through cold winters all the time, there is nothing wrong with your oil selection. No, oil pressure doesn't lubricate an engine, but neither does oil flow. The bearings in an engine create their own pressure, in the order of hundreds / thousands of PSI, not 60 like you will see on a pump gauge. As long as a bearing has oil and is spinning, it will create a wedge of lubricant. The flow through it is determined by the amount of leakage occurring, obviously a lot less with more viscous oil than with thin oil, but still getting lubricated just fine.

I appreciate all your input guys. If anything I think a new battery is going to be put in in the new future, it was tested and was a little low. Maybe that will help the sloowww starts especially when cold. I will probably continue to use 0w20 TGMO, PP or maybe even Mobil 1 Advanced Fuel Economy. Filters will most likely be either Honda OEM, Ultra, or Tough Guards.

That happens here all the time, too. You nurse a battery through the summer with the odd hiccup. The first cold snap hits, and the next thing you know, you're stranded.

This is why I don't mess around with batteries. IF the charging system is in order, the first time the battery doesn't perform up to normal standards, a new one goes in. Much cheaper than a tow bill or missing time at work.
