What are all the group 5 brands available in 5w20? Where does Amsoil rank?
So how do I tell what group a oil is in?
If I remember correctly it says that under the 2500 part, I'll have to double check when I get home
Sent a email to Royal Purpel asking for info on their product , this is what I got...
Me: 5.7L Hemi Dodge Ram: Can you tell me what group or class of oil Royal Purple falls into? Is it a Group 3 oil? Would I benefit from switching to a group 5 oil?
RP: Good morning Lance,
All Royal Purple engine oils are full synthetic except for our break in oil. Royal Purple synthetic oil formulations are proprietary. Royal Purple synthetic oils use a proprietary blend of premium synthetic base oils, including groups IV and V. There are advantages and disadvantages to each oil group, by using a proprietary combination of these groups instead of just one or the other, we can create a base oil starting point which offers significant advantages like superior performance and protection.
If your 5.7L Hemi powered Ram pickup is past the warranty period, we do offer an oil with an even higher level of performance and protection. Royal Purple HPS 5W-20 (part #31520, quart bottle) offers a significant upgrade in performance and protection.
HPS: HPS
Synerlec: Synerlec | Lubricant Additives | Royal Purple
Most of your local stores will likely not have HPS in stock and right on the shelves. However a special order of HPS can be done at your local NAPA and O’Reilly’s stores. HPS oils are also definitely available on line and shipping at the following performance outlets:
Lucky7trucks.com: HPS High Performance Street Oil - Lucky 7 Truck Accessories
Summit Racing: http://www.summitracing.com/search/?keyword=royal purple hps&dds=1
Pace Performance: Royal Purple HPS Street Motor Oil

Thanks for choosing Royal Purple and have a great day!

So.... just bought mg used 2009 ram. 5.7 hemi. 75000 miles. No history of the oil. I had a tundra with 287,000 miles. Knocked like a diesel when started but in 30 sec was fine. Annoyed the fire outbid me. I want to make sure the ram never does this. I know I will do redline in the tranny at 100k and in difs and transfer case. This thread has convinced me to swap from the castrol gtx. I have used for 200k miles to amsoil or redline. Thanks. Now to tell the boss I need tto do a $100 oil change. But that should last me 9 months. Where I used to spend $40 every 3 or 4 for the gtx and ssome Lucas.

Correction. The Redline at 25000 would be annual. Amsoil would be every 10k I believe.
