Engine oil VALVOLINE or FUCHS

We've been running the valvoline restore and protect oil lately in our fleet of cars and have nothing but positive things to say. Slowed down some oil burning on our high mileage scion TC and no complaints from our other vehicles, including my turbocharged 200k mile 09 focus.

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.

4.5 L is the Ideal for Mazda 6 2.5 non turbo, I'm from the same country as you. I'm using fuchs titan 5w30 for two years and I recommend you do the same, I noticed quieter engine.

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.

I've posted my UOAs on TDIClub and BITOG. The factory fill was additive depleted at 5400 miles. The Fuchs 507.00 in the next fill was good for 7-7500 miles. It might have gone longer, but I changed it out in advance of a long trip. Bottom line is that preliminary evidence is that the 507 oils are inadequate for extended OCIs in the 3.0L motor.
