Oil Question
Just curious I see a bunch of posts and people use all different kinds of oil. Just wondering which oil you found to work the best and stuff like that. Also I have a question too... I'm using 5w-30 full syn and I'm thinking of going to 10w-30 full syn both Mobile 1, will that have any effect on my engine changing the oil or do I just have to make sure to empty it good before I add the 10w-30? Also will a slight mix if it isn't emptied out all the way effect the engine. Also I know it depends on where you live what kind of oil should be used. I looked up other threads but they kinda dated so I'm hoping for different opinions.

Both can be mixed no problem. 7.5w30? Just kidding. If you aren't using any oil, it probably doesn't make much difference. I think the recommended wt. is 10w30 so that's what I'd use.l

I usually use 10w-30 simply because it is the recommended weight. However, I accidentally purchased and used 5w-30 for my last oil fill, and I haven't noticed any difference. I'll be going back to 10w-30 next time, though.

Been on here 36 days and already asking the oil question.
It's Mobil, not "Mobile". Run 5w30 or 0w30 oils year round for better cold start protection.
Unless someone can provide UOAs you'll never know which oil is best. It's impossible for anybody to tell if their car "likes" a certain oil without a UOA. All the guys that say M1 is best, or Amsoil is best, aren't going to help you pick an oil any easier.
The information in the oil journals is not outdated, read it and learn from it.

The best oil for your car is the oil that says "I know that this oil is the absolute best that I can put in my car" oil.
Not only do we have to treat our car to what we think is the best, we have to treat our mind.
Name brand oil changed regulary will help our cars and ourselves.

Because Shell is best 
It is!
Allthough, being a thin-oil-advocate, I would like to agree, I guess it's not going to hurt anyone to say this:
Most would consider starting at 70F to be a warm start, but IMO it isn't.
It is true that "a" 10W-30 oil may be thinner then "another" 5W-30 oil at 70F.
It also could be the other way around.
0W-30 oils are usually always thinner, probably also more expensive as those oils are usually a full (and true) syn oil.
Currently using Shell Helix Ultra X 0W-30.

Helix Ultra and Esso XD3 are two oils that I wish I could find here in the states.
