I've been reading up on performance gains after using Auto-Rx, and decided to use this for marketing.
I had a customer in today, who was complaining about performance problems and his engine feeling slugish (vehicle's a 04 350Z). He was using thick oil in his engine for a while (Veedol 20W-50) and we switched him to Motorcraft 10W-30 (recommended viscosity) with a bottle of Auto-Rx. He will be reporting back in 2,500 miles. In the mean time, I'm wondering what sort of gains he should expect from this application.

Providing this engine is under 100,000 miles (1 bottle application) his compression will come back to near normal while his combustion will be like when the engine was new. When you clean out the ring packs you can expect this type performance.
If this engine is over 100,000 miles you will need to do a second application.
Your customer should go on Auto-Rx Maintenance Program and keep these gains.
Why the Maintenance Dose?
You have just finished with a cleaning and rinse applications, to clean up the motors internals with respect to harmful deposits, but you are really stopping at third base. Early on with Auto-Rx we had suggested running a clean and rinse cycle every 25,000 miles to keep a motor deposit free. Over the last 3 years we have realized that it is more effective to run a smaller dose of Auto-Rx with each oil change.
In addition to keeping your motors vital internals clean, Auto-Rx has shown to reduce wear, as well as providing for a lower coefficient of friction than that of motor oil alone. With just three fluid ounces in the sump, enhanced lubrication is provided as well fuel efficiency. So why wait utilizing the Auto-Rx benefits every 25,000 miles, when you can have it working every time you turn the key.
The maintenance dose has shown excellent results through used oil analysis, with both conventional oil runs and full synthetic oil, with extended drains.
I've read on BITOG that the Nissan engines do like a bit thicker oil, such as a 5W-40, 10W-40 or 15W-40.
The Auto RX probably adds enough extra protection that the 10W-30 should be fine (I've read of spun bearings with 10W-30) but I think that he should go back to a thicker oil after the Auto RX is done.
We just went with what the owner's manual specifies actually. The vehicle was an American import and has only had 2 oil changes with 20W-50, so we reckoned it would be a good time to switch back to the factory recommended specification.
The Shell Rotella you specified isn't available in our market, but maybe Castrol Edge 5W-40 (Group IV) would be a good alternative for him to use with the maintenance dose.
