## Questions & Answers

**Q: does this still have extended oil change intervals like the API 5w30?**
A: While I don't have any first hand experience with API, I have always used Royal purple hps. I have personally gone 10000 miles between changes, and the oil is always clear, like new oil. HPS also has high zinc and phosphorus levels, which are key ingredients for anti-friction. I have no doubt this could do 10k to 12k miles without issue.

**Q: Anyone using this oil on a high mileage engine? If so, what's your current odometer and how long have you been using it? What were you using before?**
A: Ford Expedition. Bought it with 74k. I currently have 210K. Same engine and tranny. RP since the day I got it. Larger tranny pan. Run it in transfer case, diffs, tranny, and engine.  RP was the only oil that actually kept my Hayabusa from watching the temp climb on those hot Texas summer days on the red lights. That was my first experience, never will use anything as long as the product stays the same.

**Q: Can I use this oil in my Harley twin cam engine, which does not share oil with the transmission or wet clutch?**
A: I used regular Royal purple 20w 50 on my Electra glide 1450 FI from the 500 mile break in oil change very happy with it over 50000 miles on the engine no problem

**Q: would this 20w 50 help raise oil pressure?**
A: Trying to replenish oil pressure is only cured by fixing the root of the problem. Running thicker oil on a tired engine is merely a bandaid, and you simply raise the level of carbon build up in the engine while doing so. I've used marvel mystery oil in old farmall tractors with stuck piston rings and sticky valves and after 1 tank of gas the tractor obtained almost all its normal compression back along with oil pressure. Might be worth a shot to try
