Ok guys, I can't afford my beloved Royal Purple this oil change. Its been a year. I need to oil change my truck, I would say. Even with only 2000 miles on the oil, I feel it's time simply on account of age. (Albeit, truck did sit a bit in the summer) Walmart didn't have my backup oil, Castrol Edge 5W30 in jugs so I settled on a 5qt jug of Rotella Gas Truck 5W30. Never tried it before, but I don't think it'll do particularly bad either.... Mind y'all, I live in Fresno CA (very hot in summer, winters are borderline ~32F sometimes), I do short trips, lots of idling, towing, and drive down dirt roads frequently. Other house is in midpines up yonder in the hills. The dilemma I'm facing is they didn't have RGT 5W30 in single quarts. So I bought a quart of Castrol Edge and a quart of Hyper-Lube instead. The latter is because I notice a bit of a ticking noise at idle, and from experience I've used HyperLube on other vehicles without catastrophe. So my question is... will putting 5 qts of RGT 5W30, a quart of Castrol Edge 5W30, and quart of Hy-per lube be harmful to my truck? I plan on running this medely of stuff for a few months/3k or so then switch back to Royal Purple. Thoughts? Part of me says "Put it in and send it. oil is oil" -the other part of me says "Mixing 3 oils may not be too smart" Thanks in advance?
