Crickets Got Louder... :(

[JFox]

So I went ahead and changed my oil at 3,003 miles. I put in ENEOS 0w-20 and a Subaru filter (the black one).

I've been running TCW3 two-stroke oil in the gas (actually improved everything BUT the crickets, unless maybe to a small degree). Third tank since starting the TCW3 and I was finishing that tank up when I changed the oil.

Now, after about a hundred miles into the oil change, the crickets have gotten LOUDER than before. Maybe it's just a coincidence, but for some reason they're really, really loud now. I can hear them inside the car with the windows up.

Just in case, I went ahead and filled up the car and put in my normal 2oz of TCW3 (1oz per 5 gallons), and even added an extra half-an-ounce of the stuff just to see if that would help. Drove home (about 30 miles), and they're still there, unfaltering in their chirping.

This is a 2014 model, purchased in March.

Can you post up any reliable information about why and how running two stroke oil in the fuel is going to do anything but foul the fuel system?

I understand the logic but with how sensitive the DI injectors are you have balls.

I wonder if its pinging since 2 stroke oil lowers the octane rating.

The crickets get louder when the temperature is higher which might be why. Also I noticed it may be louder when your gas is low (maybe because the TCW3 wasn't mixed uniformly?).

Assuming he is using 2oz per 10 gallons I doubt the octane would lower enough to matter. I think someone did the calculations here and it was less than a .1 octane reduction. All anecdotal evidence of course.

I thought mine got louder one time then I rolled down my windows and realized it was flock of birds chirping outside.

I thought I had crickets until I realized there were crickets outside my house

Serious note.. I'm at 5k miles. Car only chirped a few times but never came back. I run exclusively Costco gas... no additives other than the Costco additive.

Build date 7/13 original pump.

I do have ethanol in my gas since I'm in California.

30 seconds of searching yielded these results. I think that's enough to back up what I'm saying.

If I had to guess as to why the crickets got louder (which was the reason for this thread, not to question TCW3), it would be that QuikTrip sometimes contains a lot more ethanol than other times. Now that I think about it, I didn't notice the crickets until a bit after I filled up the last time. Even though it's the same gas station (literally, the exact same gas station - same location), it's likely that they had a different batch. I'll see if I can find somewhere that doesn't have ethanol in the gas and see if that helps any. I may also run without TCW3 to see if it gets any louder.

If anything, it's going to clean them. It definitely made things a bit quieter (not as much as the oil change did) and it definitely made all the ticking/clicking/general valve noise at anything above 5k quiet down a lot. I found the engine to sound and feel more healthy after adding the TCW3 to the gas.

It's important to realize that TCW3 is different from normal "two stroke" oil that you'd put in the weedwacker. This stuff is designed to burn completely, not foul plugs/injectors, and actually have a small amount of detergent properties.
