Awww. No fair..Nice and clean. I got globs of oil on one valve. You never told me the year of the 2AZ-FE ???? I didn't know PEA could leave a mess on a piston head. Thanks for the heads up 

Adding the PEA is the only thing I had done differently when that shot was taken. My 2AZ-FE is a 2006 which isn't supposed to have the ring problem, but I bought it used at 50,000 and don't know how it was treated. I've always changed the oil between 3-4000. It runs good. The Valvoline has made a difference in how it runs too, quiet cold starts, smoother idle.
I'm looking for the BG EPR locally. Maybe a shop can sell me a can. I can either wait out the 4 oil changes with the Valvoline (I'm sticking with it no matter what), do a soak with Berryman's, or try the EPR.
Say it with us… “color is NOT a valid indicator of oil condition. Color is NOT a valid indicator of oil condition….”I've been using Valvoline Restore and Protect 5W-30 in my Toyota with the 2AZ-FE and I'm almost 3000 miles into the second interval. I changed the first at 3000 miles and I'm questioning whether to change again at 3000 miles or go to 4000. The reason for thinking it can go to 4000 miles is it still looks fresh. The first round, it got dark quickly and 3000 miles looked dark whether I checked it cold or warm. This round, it is light brown when cold and golden yellow when I check it warm.
That it looks cleaner after the same miles is just one observation. I switched to this Valvoline when I saw the first Oil Geek video about it. It had been consuming 1/2 quart of STP 5W-30 synthetic every 800 miles and had some rattle on cold starts. The cold start rattle stopped immediately with the Valvoline. Right before I made the switch, I checked compression, fully warmed up, and got 180 psi on each cylinder and that's exactly spec. About a month ago, I checked compression again, fully warmed up, and got 200 psi. That was hard to believe so I did each cylinder twice and it repeated.
Another observation is the improvement in idle. That engine would visibly shake at idle and I could see it in the battery hold down, wiper arms, hoses. Now, I no longer see the vibrations. I even tried to measure vibration for a before and after, but all I could get with a pulse sensor was that I get even pulses out of the dipstick tube at 25Hz at idle. The dipstick itself is another observation. It wasn't varnished up before, but it is sparkly shiny now. Looking in the oil fill hole and I really haven't seen anything different.
The final observation is the consumption which is really why I switched. 1/2 quart in 800 miles before the Valvoline and 6000 miles later, that has improved to 1/2 quart in 1400 miles. I check it before every cold start and if I go into the grocery store or anywhere it will sit for 10 minutes. This seems to be improving. The first interval I saw it improve to 1/2 quart in 1000 miles. I'd like to see it just stop but I'll take a 43% improvement.
Almost forgot, my driving is mixed highway and country roads some city. On very long trips before the Valvoline I got 35MPG, AC blasting, 70 MPH. That will be hard to beat, but my next long trip will be an opportunity to see. And I'm at 90,000 miles on the odometer.
Ok,thanks, got it, it's time for an oil change then based on time. I'm at 6 months and 3000 miles. I decided on the first interval I'm sticking with VRP as my oil. It just runs buttery smooth on it and I know it's better to stick to one oil. The peaks and valleys will thank me.Say it with us… “color is NOT a valid indicator of oil condition. Color is NOT a valid indicator of oil condition….”
You have Top Tier fuel in Germany?I used to buy fuel system cleaner decades ago (Gumout All in one, Redline, 3M, Techron, etc.) and found that it is not necessary, just dump money for my ego and believe to get the placebo "feel good effect". Now, I never buy such producsts anymore since I bought fuel from Top Tier gas station.
I4 Four bangers - especially the sidewinders - are just too easy + so effective for a balanced soak - and often need new plugs anywayIf it were mine, I would do a Piston soak at the end of current interval. Then keep running VRP and go from there. It's entirely possible that VRP alone will continue to improve the consumption. Impressive results so far, love seeing the before/after compression testing.
I talked about my past in FL. In Germany, or Western Europe in general, fuel cost almost 3x, or $12 per gallon. Everything is top tier, adding 3-10x more detergent in gasoline is fraction of the fuel and tax we pay here. Especielly diesel fuel, in Europe they have much higher detergent level than the USA diesel fuel (almost no detergent in diesel fuel).You have Top Tier fuel in Germany?
Ha, yes I remember that now. You keep flipping between your American and European experiences. Not your fault, just wanted to clarify.I talked about my past in FL.
