castrol edge full syn 5w-30?

One of my favorite oils is Castrol Syntec 5W-30 but I've found the amount I change oil it's a waste of money. I use Castrol 10W-30 GTX.

I found that Mobile 1 is too thin of a oil at our oil temps and will shear far too easily and if you run the car at high RPM's, you will loose oil with the Nissan VQ engines. Especially if you use the SRM all the time and downshift to slow down, instead of using the brakes.

I used to use Mobil 1 in my turbo S2000 and the engine heat would burn it quick enough that I'd have to add oil every 2-3 days of normal daily driving. Once I switched to Castrol GTX , It held up enough to the heat that I only needed to add 1 time per week.
