Technically, the lower SAPS is spec'd for this car. Super Car is fine, though...it only lost 1/2 a quart in 10,000 miles. So, I'm not poisoning the cat or anything. But the Euro is good for 10,000 miles, and I'll probably not keep this car for more than another 10-20K miles anyway. Too many plastic pieces that get brittle as these engines age and heat-cycle. I'm getting old enough I no longer have fun upgrading those pieces to metal when they begin to leak. Funny how once those plastics are replaced, the engine is good for more than another 100,000 miles. Now, if I had a LIFT where I wouldn't have to roll around on the ground when the time comes, THEN I'd keep the car for 200,000+ miles!Curious why switch from Super Car to Euro?
