    Valvoline Restore and Protect piston cleaning: IIIH test vs. normal driving

    The first thing I noticed in the first OCI with Valvoline was no more clicky clacky in the first second or so of a cold start. Then I noticed it idled smoother, no more visible shakes. At high load, lower RPM it accelerates smoother. Before, I wouldn't call it a misfire, but I could feel...

    Valvoline Restore and Protect piston cleaning: IIIH test vs. normal driving

    When the weather warms up I'm going to test compression again and go in with the Borescope to see what kind of wear I see. I've been using Sunoco gas consistently and the pump says top tier for what that's worth. I changed the PCV and hose about a year ago. The PCV is roughly $4.00 to...

    Valvoline Restore and Protect piston cleaning: IIIH test vs. normal driving

    One of the benefits I saw using Restore and Protect was an improvement in compression. Specifications for compression on the Toyota 2AZ-FE is 196 PSI. The before Valvoline compression was right at 180 across all four cylinders. I did the compression test again into the second oil change with...

    Valvoline Restore and Protect 2AZ-FE Observations & Questions

    I'm approaching 3500 miles on this oil change. I have not added oil since December and that was 2 ounces. Since then it's been all mixed local driving of about 20 miles a day, no prolonged highway, no drips on the pavement either. Temperatures have been in the single digits in the mornings...

    Valvoline Restore and Protect 2AZ-FE Observations & Questions

    I don't get any spots on the ground either, but the other morning my BIL said he noticed an oil smell when I started it. We had the hood up and that's the area where he smelled it. When the engine shuts down, all the oil drains to the pan so the leak stops. I can see the weepy valve cover...

    Valvoline Restore and Protect 2AZ-FE Observations & Questions

    I just went out and took a quick look with a flashlight. Oil level is full, topped off 100 miles before home. Looking at the valve cover gasket seam and it has a fresh and light coating of oil all the way around and also goes down the belt side of the engine. The valve cover seam is the...

    Valvoline Restore and Protect 2AZ-FE Observations & Questions

    Well, I had some disappointing results this Thanksgiving. I had an 800 mile round trip. I started the trip with a check of the dipstick and it was tip top on the Full mark. I drove the 400 miles to Thanksgiving dinner and it needed 1/4 quart. I filled it for the return trip and about 100...

    Valvoline Restore and Protect 2AZ-FE Observations & Questions

    Sounds like you're the perfect scientist to collect that data since you already own it. Make sure you have all the gaskets needed before you pull it.

    Valvoline Restore and Protect 2AZ-FE Observations & Questions

    Another 200 mile round trip and still no sign of oil consumption. I'm in the 3000-4000 mile oil change nonsense camp. I figure fresh oil is always better. At 3000 miles I saw aeration on the stick and at lower miles I don't see that. I'm no expert but if there is aeration then it could mean...

    Valvoline Restore and Protect 2AZ-FE Observations & Questions

    Lake Speed Jr. just did a video on breaking in his new Toyota and he mentioned that he was changing the oil and not the filter. He had done a video on filters and learned from a filter engineer that a used filter is better than when a filter is new. I guess there is a sweet spot between brand...

    Valvoline Restore and Protect 2AZ-FE Observations & Questions

    I checked the oil after sitting overnight and it was still full. That was a hard 200 miles and it passed that "test". I checked my log book just to be sure and This is the third interval. Total miles with the Valvoline is 8000 miles so far and it appears to have stopped consuming oil. That's...

    Valvoline Restore and Protect 2AZ-FE Observations & Questions

    Ahhh, filters. From what I read that is a deep rabbit hole where opinions differ widely. I've used NAPA gold, STP extended life, Toyota, and STP standard. At the moment I'm using an STP standard. The first round of Valvoline restore and protect I used the NAPA gold because I had it. The...

    The first cold start after sitting for weeks was absolutely quiet. It fired up like it had been running every day.

    Valvoline Restore and Protect 2AZ-FE Observations & Questions

    He must not be familiar with the Lake Speed Jr. visit to Valvoline's R&D facility where they explained how they discovered it and then engineered it for specific properties, tested it until they were satisfied it did what they wanted. Lake Speed Jr. has explained that it doesn't rely on esters...

    Valvoline Restore and Protect 2AZ-FE Observations & Questions

    I checked gas mileage over a 1700 mile period and it gets 24.1 in mixed driving while it's rated 22 City and 29 Highway. I've seen 34 on long trips before switching to Valvoline Restore and Protect. I'm a few hundred miles into the fresh oil change and I make a 25 mile trip once a week of all...
