Engine oil VALVOLINE or OEM Honda

I really liked Valvoline, good quality, reasonble price.

Valvoline Restore & Protect or Pennzoil Ultra Platinum are also great oils to run and clear up and baked on sludge.

Buy Valvoline oil, and maybe it's a good time to switch to 5w-30 in it.

I have a 2023 Civic Si.

I did every oil change at around 8k miles which is when my maintenance minder popped up, even though the dealer recommended every 5k. No issues ever, now at 46k miles.

I only run Valvoline VR-1 40-wt in my air-cooled VWs

I tell you the stuff really works. My 2009 Matrix used to burn oil before I switched to Valvoline Restore and Protect.

i honestly have no way to prove if it works, but i started using it in my ‘98 corolla about 20k mi ago (known for burning oil due to flawed piston design) and have noticed a significantly lower oil consumption rate, which was almost 2qts every 5k down to less than half

I normally dont buy into stuff but my vette was burning oil, Id see a big cloud of blue smoke after I let off after every pull, few thousand miles of this stuff and I stopped seeing it.

My last [Blackstone-labs.com](http://Blackstone-labs.com) report came back with 1.8% fuel dilution. 2021 1.5T at 23kmiles, 6800 miles on the oil (0w20 Valvoline R&P).

I use that Valvoline, sometimes throw in random fully synthetic oils I get in bulk from an auction. I feel like it contributed to a rear main seal leak. Thinking of switching to a 5w40
