I have not found the Delo 10W30 but found Delo 30W. I need to start a rinse cycle after the initial Auto-Rx round on a '91 Mazda Protege w/ 165,000 miles on it. This oil will be in during the winter in the middle of North Carolina with lows in the 20s. I really want the HDEO in there for the rinse. Would you use the 30 wt (the recommended oil is 10W30) or mix with 5W30 Chevron Supreme? If a mix is ok how much of the 30 wt would you mix with Chevron 5W30 to approximate a 10W30 solution?
Thanks in advance for your help!
