@Burla Wow.. closing on 50k posts. A milestone and keeps us wondering if a thread about oil needs to be this long. Granted not all of it was about oil.
There were deviations into coolant, transmission, politics, EVs and quite a bit on coffee, which made me feel really sleep. Yes, coffee makes me drowsy. I'm weird.
When it comes to EVs, they're not going to save the planet. Elon is right, it is the most efficient way to power a vehicle, but not the best since it lacks the flexibility in terms of range. Blaming the shortfalls on the lack of infrastructure isn't going to help either. It takes me just 10 minutes to top up a fuel tank and get another 600kms of driving. Where's the EV with anything close to that rate of charging in and range?
I have more to say on that topic, but I will save that for another time and another conversation. We're here to talk about engine oil.
My truck is in the shop right now for a complete fluid change. However there was an issue when the mechanic opened up the transmission.
2017 ram 1500 big horn 5.7 with 8 speed transmission. I developed a chatter /shimmy in low speeds in town last week, started reading up on things and decided to check fluid level today. I waited till temp was below 90 f then took side plug out. It was so full of white oily water , about 1 1/2...

That said, I took this video yesterday after the oil was changed.
Just did an oil change with Mobil 1 Fully Synthetic 0w-40. This the second oil change. The previous oil was the same. Having used Mobil 1 for two oil changes...

The engine sounds so smooth. Dare I say it, a bit better than when I was running RL 5w30.
I was running RL 5w30 after the last rebuild. Ran it for 6000 kms and then changed over to Mobil1 FS 0w40 based on recommendations on here and BITOG.
This is the second change with Mobil1 FS 0w40.
So what have I learned going through everything I did and reading 48k+ posts on this thread.
Anyone who has just purchased a Ram 1500 (new or used) with the 5.7 HEMI should do the following right away.
1. Forget what the manual says because manufacturers are only chasing EPA ratings.
2. Keep the oil change intervals short. I'm doing it at every 5000 kms (approx 3000 miles). Use an oil that will last 6000 miles, but always change it at 3000 - 4000.
3. Use a good 5w30 or 0w40 oil as soon as possible.
Recommended oil for the 5.7 Hemis are:
- Redline 5w30 - if the budget allows and you can use it, then you can take the change interval to about every 5000 miles.
- Mobil 1 Fully Synthetic 0w40
- Pennzoil Ultra Platinum or Platinum 5w30 with Lubegard Biotech
- Pennzoil Ultra Platinum 0w40
Other honorable mentions are:
- Valvoline Fully Synthetic 5w30
- Castrol Edge 5w30 / 0w40
- Castrol Magnatec SUV 5w30 C3
4. If you have a Hemi lifter tick, and you don't want to do a rebuild, then use Redline HP 5w40 first and then RL HP 5w30 continuous after. Another recommended combo is Pennzoil Ultra Platinum 5w30 with Lubegard Biotech.
I can't recommend Amsoil SS 5w30 because my engine didn't sound too good with it and the cost of the oil for me here in Dubai was about the same as Redline. I only used it because Redline was not available. Maybe I can give it another try.
Considering Mobil 1 FS 0w40 is readily available anywhere, I think that it is the best choice for anyone after Redline.
Edit: Considering the recent posts about tin being in Redline, I'm wondering if I should still keep it as my #1 recommendation.
