Cold start up tick and rattle!
Just did an oil change and wanted to try Royal Purple vs. my long standing Mobil 1. Both 5-30.
Why? Curiosity, not much else. I recently read a good article on the various brands of oil out there and identifying these two specifically, the article found them to be very close in regards to protection, suspension of contaminants, etc. the article did indicate Mobil 1 being superior to many on the cold start up. It also indicated Mobil 1 was a true full synthetic where the royal purple was a mineral oil base with synthetic additives. My first observation was the Royal Purple was thicker than the Mobil 1 10-30 I had on hand. Second, I also noticed my temp gauge running about 2 needle widths higher than with Mobil 1. Now, on cold start up this morning, Holy Hell engine knock & ticking like crazy! It did go away after about 5 seconds. Between the temp gauge and the cold start up noise (which was minimal with Mobil 1), I will be rolling back to Mobil 1 on the next change. I may even drop 1/2 quart and top off with Marvel Mystery just to thin it out a bit. Anybody else experience anything like this? I've used Mobil 1 for the last 15 years at every 3k. I know, I know, many of you think it's a waste of money. And there is another group who is die hard Dino lovers. I'm just interested in engine knock on using royal purple. I used RP in my Diffs and noticed a difference in how easily the lockers engage and disengage. Just thought I would try the engine sludge too. |

I use mostly penzoil in my 2012. I now have 50,000 miles. I change using synthetic every 5k. In addition to penzoil I have also used castrol once and the oil in there now is royal purple. I can honestly say I can never tell any difference among any of these oils as far as sounds and performance go. I don't use Mobil 1 because it does not carry the Chrysler MS certification. I don't want to give chrysler any wiggle room to deny any claims since I have lifetime warranty.

My 13 is noisy for 30 secs on start up. No ticks, but clearly noisier. No issues but something I noticed until warms up , high idle down to 1 k. 2013 7500 miles.

I use mopar filters and penzoil synthetic 5-20. Just sounds a little more mechanical for 10 sec. Don't think anything wrong, will have to listen to a used one next time I'm at the stealer ship

Well, after multiple cold start ups, including a 4 day rest at the airport, followed by a 3 day rest at the airport, no other cold start up noise. It actually sounds better. The only thing I can think is the anti drain valve stuck or the system just needed a good run to get oil in all the right places. :)
