When are you and your brother coming out to C4/ZR-1 Gathering at BG again?

According to what was posted previously, the M1 5W50 available in Spain is an API SL-rated oil BUT, is exempt from the ZDDP limits in that category because it's a 50-wt. According to ExxonMobil information I have on file, zinc is 1000 ppm and phosphorous is 1200 ppm.
Keep in mind that no LT5 needs an SAE 50 engine oil unless the duty cycle is severe in very hot weather. For normal street use and even street high-performance use, I would not recommend a 5W50 in an LT5.
Also, LT5s are OHC engines with direct acting bucket tappets. The loading on the camshaft lobes and lifter faces are far less in an OHC valve train than they are in a pushrod valve train, thus, there is no need for high levels of ZDDP.
