Valvoline Restore & Protect 5w30 2023 GMC Sierra 1500 2.7

[Ayrton]

I worked 8+ years in an automotive testing facility and we had a book on how everything can affect efficiency i.e. tires, wind drag, oil, etc. When I read about a certain oil (or additive) yielding 2-3 or more mpg, I wag my head and chuckle. Impossible.

In some ways, I have been disappointed with R&P. However, on my first run in the spring until after my second fill with it this fall, I do believe I saw MPG increase in my Volvo. Of course, I was also coming from thicker Euro oils.

2-3 would be a lot though. Even with my gasoline log I keep, it's hard for me to say just how much it helped. Some quick comparisons form the same week in different years, looks like 1-2mpg. Again, that's coming from a 40 weight. However, there's so many factors, that even I can't say with certainty it helped.

This is really amazing and makes me glad my truck is capable of crushing EPA estimates.

ANY vehicle should be "capable of crushing EPA estimates" on a pure highway run if not speeding. The reason: the highway MPG test is NOT a cruising-along constant speed test. It has many accelerations and speed changes...and I believe even a stop or two (it's been a while since I looked up the test requirements). IIRC, the average speed of the highway testing is 48 mph because of the stops and speed changes. A 2018 Camry I had would get in the low 50 mpg range with three adults in the car on a pure highway cruise by staying at the posted speed limits. When I drove it for long distances with three adults and luggage, I could AVERAGE in the mid-70 mph range (including stopping, because I was going the low 80's most of the time) and still return over 40 mpg.

I'd believe the earth tilted before I'd believe an oil gained 2-3 mpg over other modern synthetics.

Nevertheless, I just filled my 14 GMC 5.3L DI, 116,000 mi engine with VRP 5w30. I'm looking to clean up the rings and possibly reduce the 1qt/3500-4500 mi oil consumption. I could give a crap about fuel economy or Dexos licensing.

Give us a review after 4 OCIs of VRP Roanie.
In the meantime, Merry Christmas to you this year, next year and probably the year after.

The earth IS tilted relative to it's position to the sun as it orbits the sun every 364-something days. That's why we have Winter and Summer. But I agree about 2-3 mpg increase due to oil alone...ain't happening.

I just reached 500 miles on the oil and so far maintaining the increased FE. Have hand calculated the mileage to verify and yes getting about 2mpg better over AC Delco and QS oil.

Yes something is happening but I need to test with standard Valvoline FS and PP to see if this maintains. Maybe AC Delco which is most likely Mobil isn't as good idk?

The engine is breaking in ?
