The XPR is a higher end oil aimed at racers. Most synthetic oil blenders offer a "racing oil" and mainly they are straight weights without detergents added. Depending upon the synthetic base oil used some companies like Royal purple will select a "better" and usually more expensive base oil for their racing oils.
There are better choices out there. Redline for example makes some of the better "racing oils" although you should never run a true race oil on the street due to the lack of detergents in the oil. Redline uses Group V(polyol ester base stocks) in all of their oils. Royal purple uses group III/IV and their oils have shown to be not very shear stable via UOA. Its not a terrible oil but there are much better offerings out there. Motul is another company to look at. Both Redline and motul are very pricey but in this case you get what you pay for. Polyol esters are used to lubricate jet engines and have been used for years in F1,INDY, NASCAR offshore you name it.

A really good 40wt is Mobil 1 Ow-40. It flows vey well when cold and is a heavy 30wt if you look at its specs. It is widely used by many race teams and can be found anywhere. But remember its not a must. A good synthetic would be automatic in a turbo car.
Conventional oils have come a long way since the 80's. They protect in 95% of any situation. The other 5% is covered by high end synthetics like Redline and Motul(usually racing environments).
Yeah 3000 is way early unless you are tracking the car often. Then its wise to change because of fuel dilution. But you know what they say, whatever makes you sleep better at night. Personally in my camaro I have always changed the oil early. Call it OCD or whatever, Cause I know better studying oil for so many years. If it doesnt hurt your wallet 3000 mile syn oil changes are never going to hurt your motor.
Check out blackstone.com You can send in a sample of your oil(they provide a free mail order test kit) this way you can gauge the life of the oil you are draining at 3000 miles. The test runs about $32 for a regular test. Its a good way to see how long you should run your oil. Every setup is different as you know. If not just keep doing what you have been. No harm in it at all.

^^^ lol. i do not think it is an option for me because i run 15w40 in my camaro and my truck takes 10w30, 15w40 gets a little to thick for the winter for a gasoline engine.
