Thanks. I may do an oil change next month with M1 HM 10w30 and see how it does. |

You are welcome. Of course all that may be just propaganda. 10W30 Motor Oil in Transmission? Manual trans. only.

I am not going to dump motor oil into an automatic transmission. |

I run 0w-30 Mobil full synthetic. Been using it since I rebuilt the motor in 2011. I have 100k on the motor, and if you take off the filler cap and look inside it's as clean as whistle. |

Um no... Ow30 is thinner.. Winter.. 5w30 is thicker summer Edit... Explanation , oil thins when it gets hotter. In the texas summer , I do not like how thin 0w30 gets.. Edited by Justahoby, Aug 19 2014, 04:49 AM.

I use Castrol 30w with a Purolator filter. The slightly thicker viscosity when cold has helped it from puffing smoke on start up. Also, it's usually 80 degrees when it's 'cold'. |

I use Valvoline 5W30 full synthetic, and change between 8-10,000 miles. I commute over 100 miles per day, so they're mostly highway miles. There are usually as many opinions on oil choices as there are on tastes in music. Find a good quality oil that you are satisfied with and stick with it. My dad got me started on Valvoline building race cars and hot rods over the years. The old "Chevy Power" factory manual/catalog specified using an ashless oil for high performance applications, and at that time, the only choice was Valvoline. Granted, this was long before the advent of all the synthetic technology we have available nowadays. |

I agree with ONEHARDHEAD. Pick something and stick with it. I've heard that it's better to stay with one brand of oil than switching back and forth. Do I believe it? Ehhh, nah. But it can't hurt. I use Brad Penn 10w-30 in my Honda. It has a ton of great additives for my application. I'm not sure if there is anything in particular these motors like to have. Driving style makes a big difference. I change my oil at least every 3,000 miles because I drive 1.5 mi or so to work. That is considered harsh driving since it barely gets to operating temperature and it's a lot of stop and go. The guys making hour long treks to work can probably squeeze the 5,000 miles or even 8,000-10,000 miles out of synthetic. |

I have always used Castrol GTX dino in all my vehicles. Habit, I guess. 10W-30 + Purolator PureOne filter. |

The "5w" in 5w30 is the WINTER rating. It means zilch in summer. You may as well run 0w30 all year long since it's the same oil at summer temps. Like you said, oil thins the hotter it gets. Here is a chart on oil velocities. I am only paying attention to *w30 weights. Unless you are starting/driving the car in -20 or lower (52 degrees below freezing!), 0w30 is overkill for winter temps. I mean, I guess it does no harm but if it's costing you more than 10w30 or 5w30, you may as well use one of them instead... unless you live at the North Pole. ![]() ![]() Edited by Cubey, Aug 19 2014, 12:08 PM.

Mechanic for 20years... I been around this oil viscosity, and also have a degree in engineering, understanding viscosity index numbers outside of viscosity , and calculating friction factors for changes of temperature is some of what I know 0w30 for winter, which in texas is a summer in your cold state 5w30 in summer, which even the high temperature should be the same, is freaking hot here. I would not let no nonsense tell me otherwise Forget eggs frying on the sidewalk, and people up north bragging how cold , there is only so much a viscosity improver can do before continuous heat breaks it down. If you are running an oil gage and it reads higher on a cold start with 5w30 than 0w30, you are getting a false reading based on wt of oil. It will be by no means be comming out of the pan quicker, unless you have a worn oil pump, and getting to the gaugeat a higher read pressure has no meaning in what tolerances within it is getting too. |

According to your picture. It shows 5w30 starting a -30 going up 0w30 arrow goes below 30 also this is not for a 5w30 engine. I am willing to bet this is a generic recommendation for a 10w30 engine.. even your graph backs what I am saying |
