Engine oil VALVOLINE or Eneos

I was a diehard Mobil 1 Extended Protection guy, but fell into the hype about Valvoline Restore & Protect. Tried it on my 2015 Mazda6 2.5 with 95k miles and have to say I'm impressed. I bought it used, it was using about a quart every 3k maybe, and had some blowby. Otherwise ran good, had several 40+ mpg tanks. 

Switched to R&P, after 1k the blowby went away and after 3k it looks like it stopped burning oil.

Mobil 1 "eh" oil. It's okay, not bad like royal purple but better off on Vavoline or Pennzoil. Also Motul but that's expensive shit. Amsoil is okay, it's one step above OEM.

My 2007 camry is on 22k km (engine 2AZ-AE). No oil burning so far. Always been using penrite 5w-30 while servicing between 5000 to 8000. Only one time had burning smell while running engine on Valvoline 10W-30. Changed the oil at 3k, after that smooth as it was.

Valvoline full syn high mileage and black OEM filter - 113k miles and it doesn’t eat any between changes.

Eh if it’s VW approved then it’s fine. I just use Castrol Euro or Valvoline Euro and haven’t had any issues.

Last oil change I put in Valvoline R&P 5W-30. The final 500 miles before the oil change I added Rislone and it changed the color of the oil from light to dark brown. When I got the car it was using a quart in about 2200-2500 miles.

Been reading user anecdotes about R&P for a while now, and it's like 98% positivity among those who reported oil consumption before using R&P and seeing substantial improvement after.

My Miata isn't currently burning an oil at all, but I put R&P in it and I intend to change it every 3k because it makes me sleep well.

If I used the Valvaline High Mileage Blend oil (red bottle) it would leak less oil.

Might I suggest Valvoline Restore and Protect. It is magic in a bottle and it's anti wear package is off the charts with oil analysis.

I refill about 1/2 qt of oil every 2500 miles.
