[neverbored]

I recently bought coach 165 and had the oil and coolant changed before I drove it from Las Vegas to my place 5 hours away. I gave the shop Delo 100 but they used 10w40. How urgent is it for me to change to the single weight?  I’d like to put another few trips on it before i  take it in to have the oil pan seal replaced and then put in the correct oil. I’d say probably 16 hours of driving. I have a mobile guy that can change the oil but cannot do the seal and don’t want to waste that expensive oil. The engine is in great shape with 70,000 miles. 
Thanks in advance,
Mark
