Engine oil Question?

If your engine is still good and you use too thick an oil, there will be insufficient protection at operating temperature. It won't fail straight away, but it will start to burn oil earlier in the long run.

HUH? and why would u use a more runnier oil when your car starts blows smoke. doesnt make any sense...
i hope u know what the upper range figure means right

Upper figure indicates the viscosity for 100ºC, lower figure indicates the viscosity at -18ºC. With our climate, we can use 0w, 5w, 10w and even 15w because we rarely go below zero (if you live in the mountains where it snows, then you'll need 0w, 5w or 10w). At operating temperature, the upper value is more important and a higher viscosity at 100ºC assists in reducing blowby in older engines.

Agree on the Mobil 1 ....and if I need oil on road trip somewhere, Mobil 1 is very easy to get.

chosing a good oil is a major contributor to your engine's performance and longetivity.

you can chose the viscosity from this chart:

Make sure you use an oil that says "API service SG or SH", this oil is formulated to help your engine use less fuel.
as you can see 5-30 is not recommended in 40C heat in the summer. 10-40 would be the best way to go during winter, and 20-50 during summer.

Super thread revival....
Which car is that chart from? It varies for each model. Here's the one for mine:

You should use SL or SM oils. If you are in a pinch, SJ will work but you might get a little gumming depending on the oil's formulation. Oils from the SG and SH (for engines before 1996) era might gum up under the heat and relatively high compression of current engines.
