I heard all the rave about Royal Purple engine oil so a few months back I bought a few quarts and thought I'd give it a try albeit it was the most expensive engine at Pep Boys. So far I put in over 4K miles since the oil change. I was once told by a mechanic that I can run 6K miles on full synthetic oil. Can I put in anouther 2K miles before my next oil change? Before using synthetic I'd just buy the cheap Proline oil/filter and have an oil change every 3K miles.
Also, my family and I will be traveling from SoCal to the Bay Area for Christmas, what's the best tire pressure for cross-state traveling? :drive:
Any help and advice will be appreciated. Thanks and Merry Christmas! :mullet:
