I put Lucas oil thickener and now there's really loud ticking (valve noise i think)
Hi guys. I'm new here and I have a 2005 Acura TL. great car. I went to do the oil change about 3 oil changes ago and the engine wasn't too loud but it had some valve noise. went to the auto parts store and asked the guy what he would recommend. he said Lucas oil thickener would quiet them down a bit. I put it in and did the oil change. about 2 days later the noise got even louder and as i continue to run the car it sounds even more horrible. It's so noisy now that it sounds like chirping and valve floating, almost like a diesel but louder. I asked a technician at amco and he said that I shouldnt have put in that oil thickener because the valves are somehow calibrated to oil's thickness or something like that. when it turns on it sounds like one of those wheel of fortune spin wheels with the lever that signals what the person has one..that noise of the plastic needle hitting all the little sections of the spinning wheel. Ive noticed however that aft 2k they go completely silent as if there were secondary valves that have nothing to do with the primary. Has anyone ever encountered this problem? what is wrong? and can anyone recommend what I should do before I take it to a mechanic? thank you guys

Change the oil ASAP to the recommended 5w20 and see if that helps any.

Nothing to quiet down in the valve train, no lifters.
As stated above, put the 5w-20 in, change filter and see results.
If still noisy best to get a stethoscope, long hose, or long screwdriver to find the area of the noise, but a valve adjustment may be in order.

As the others said. Change to 5w-20. What's the mileage on the car? As Turbonut said valve adjustment might be in order. Typically around 105-115K miles especially when noise is noted. Not uncommon to have them checked when the timing belt (TB) and water pump are done. (Assuming you are > 110K miles do you know if/when the TB was done?) If you are not a DIY person then I'd find a well respected Honda/Acura independent in your area. A good indie will know the brand and what aftermarket parts hold up and when OE parts should be favored. Or better they'll just use OE parts and charge far less labor than a dealer. IMO Amco or any of the other chains should be avoided. If they are your only choice then I'd even say go to a dealer before them.
In general additives aren't such a good idea and most here will probably recommend you don't use them. I see you are new here so welcome! and other things you might note is that for oil you can use any 5w-20 that meets the specs in the owner's manual but for coolant, power steering fluid and auto trans fluid we tend to favor actual Honda/Acura stuff. It may cost a bit more but considering it's not that often you need it it's really not that much extra.

My best buddy from high school owned an auto parts store for 25 years an swore he'd NEVER put STP Oil Treatment nor any other thickeners in any of his engines.

I have only owned one car where I used that thickener stuff....it was an '81 Olds Cutlass with the old 3.8 V-6. After a thousand or so miles on an oil change, the oil light would flicker at idle. A bottle of STP every 1k miles helped that out quite nicely. That car was such a POS, but it is all I had and it got me around through my teen years. I gave that car to my Grandpa when I went to college. It had a decent bottom end knock by that time, but he drove it for another couple of years with no issues.
Now...any modern car. Hell no. Not unless you know you have other issues that you are trying to hide/mask and understand any "fix" it brings is only temporary.

stop putting snake oil in your car.. replace all the oil with fresh oil and valve adjustment.

You may want to check all of your sparks plugs as well, and soon. It could be a loose spark plug making the noise, the oil thickener could just be a coincidence. Pretty easy to check the plugs and make sure none of them are going to shoot out of the block.
