See if you can find Vavoline VR-1 20w50 Racing oil there. Its for HOT WEATHER USE ONLY. 80 F to 120 F outside air temps. Has lots of Zinc and Moly Anti Wear Additives. CASTROL GTX HAS A SPECIAL EUROPE SPEC OIL NOT AVAILABLE IN THE USA. 20W60. MADE FOR HIGH REV GERMAN TURBO ENGINES. GOOD STUFF. Otherwise use a Zinc Replament additive added to 10w30 oil. ZDDP additive found here. And LUCAS Zinc additive in a small 4 ounce bottle.
