Mobil 1 is a name brand, what you need to know is the viscosity. Make sure your oil says 20w50 on the bottle. That is what most people use in their Harley.
if it runs ok above 30, suspect bad carb main valve or dirty float bowl.
Yes
In OK they want like $1200
You will probably be OK as long as you don't change the intake.
Can 99 jeep run ok with-out catalic converter
Well, to tell you the truth, Mobil 1 (Full Synthetic) oil is the best lubricant on the market. You spent a lot of your money on your Porsche. You may save a bit of money on the oil changes, especially at 10-quarts per change, but by using an inferior product you WILL pay for it in the long run in service bills. The oil specified for the car is 0W-40 Mobil 1. My suggestion is to use it, it will pay benefits in the long run! Never had any problems using it, Ever! Not sure who makes the oil you asked about, but I have been using Mobil 1 in all my vehicles for over 20-years.
Yes. Check your owner's manual for proper viscosity requirements for your area. Usually 10W30 will work for most climates.
20W50 designed for an air cooled engine would be the norm. However, straight 50W or even 60W would be OK in warmer temps.
If it filled completely it can cause excess pressure and leak over into the combustion chamber. If the level is below the return fitting it should be ok.

The answer depends on how good you are at arithmetic. 1175 or 1180 if you are very good; 1150 or 1200 if you are good and 1000 if you are just OK.
No.
