Royal Purple change its blend? They are now sporting an ASE badge on the bottle, reading the bottle you find its a GM approved Synthetic ... The bottles also had a larger mouth on them... I have both bottles at my house, "will take a pic when I get home".
So anyone know what the situation is?

Just called RP and confirmed they have a new line of oils, the HPS oils are what we want to use for a better option to the new blend. It comes with synerlec, and is even superior to the previous formula. Also they told me that their oil fikters are manufactured by the same company k&n uses but theirs filters finer and is rated for 12000 miles or 12 months. So 2 oil changes same filter.
Feel free to call and validate. This was from the mouth of their oil tech.

It's still overpriced. It's been proven over and over that German Castrol is the best oil for LS1s. As far as the filter goes you are correct. They are made at Champion labs. However the RP filter is a unique material that allows it to go 12k. The Mobil 1 and K&N filters are identical aside from the casing.

I can get the Castrol on sale local for "oil change specials" from $29-35 with a filter. Cheapest google finds HPS for is $7.40 plus shipping (if it's legit). Still need a filter ($8-15) and still have to pay shipping ($10+).
You would need a real world consistent difference of almost 1 full mpg for the entire oil change (assuming it's 5000 miles) just to break even. And if you want to convince me there is a difference of more than 1 mpg between 2 premium synthetic oils over a 5000mile test I will want to see some serious proof involving a controlled lab and a dyno.

I was once a huge Amsoil fan, until I started adding how much oil was costing me. I burn quite a bit through the PCV system. Amsoil is expensive to keep stocked. I now run Advanced Auto's self labed synthetic after the guy who dynoed my car told me that's what he's been running for years. The cost difference is rather substancial, and the AA stuff is easy to get, and is $4/quart when on sale. I haven't noticed a single difference since the switch. I also switched to K&N's filter with the 1" nut - so much easier with Long Tubes to change it out. Amsoil is a great product, but I was tired of paying for it ($20/year membership), the oil was still expensive, and then add shipping it just wasn't worth it.

I am highly skeptical of an accurately measured and repeatable difference. Trying to accurately gauge MPG, driving habits, fuel quality/consistency, and idling time over a 3000-5000mile oil change would be fairly involved.

Dyno i could care less about. My individual tests were done over about 40k miles with the same car, same daily commute same ultra conservative driving style. Royal purple avg miles to tank "65 mile commute 99% highway with cruise set at 70" 430mpt with a record @ 460mpt. Castol avg miles per tank 390 with a peak 420. Mobile 1 I dont recall off hand but it was similar to the castol. Mineral oil was around 375 miles per tank. Over the course of 4 years at the same job, it really does add up. Believe what you like, but Everytime i change oils even for 2 or 3 changes i lose mileage on the same daily commute. When I go back to RP i regain my mileage. You tell me then how it can be explained. This is in my daily, and I completly dismiss tanks when i drive aggressive and I fill my tank everytime until it cannot hold any more " fuel spilling out practically" and I run it to the same spot right on the "e" i then count how many gallons i use to fill up, divide by the miles, and subtract what i filled up with minus tank capacity to ensure I stay accurate. Trust me I am extremly thorough, and meticulous when it comes to fuel economy, and oil on my Camaro and these have been my results. If they dont work for you fine, I don't care.
I am on car number 3 from my switch from M1. All 3 cars have seen from 1-4 mpg over other oils. My next experiment is amsoil. An oil I have never used. This castrol will only go for another 2k miles before i go back to RP for more baselines. I dont need a labratory or anyone elses criticism of my results to convince me of what I've seen for myself..
All that being said, they changed their blend anyways so its not even the same oil... Which was the point of my thread.
