YES there is something you need to know. You should use a "flush oil". I.E. Drain your oil and put in some cheap regular 0W30 and let your car idle for like 15 minutes, then put around in it for like another 30 minutes or so... keep your old oil filter on. THEN Come back, drain that oil, and put in synthetic. This way all the shit that breaks loose from the thinner oil won't be floating around inside your engine.
