Hello everyone. I am new to this bored and I know I have a lot of reading to do but I have a question. I own a 96 honda accord EX Sedan and I have been running Royal Purple now in my car. I need an oil change and I was wondering I have 2 bottles of RP 5w-30 can I mix that with M1 5w-30 and make it for another 3000 miles?
