    I’ll probably put 10k or so on it between November and April then drive it a few hundred a month for the rest of the summer. The usage doesn’t seem to be linear. It idles a good bit in the winter usually 40 min per day min

    I put 17k on the company car this year so far. It’s 80 miles round trip to work 5 days a week. This car has only seen 3k miles since April. I drive it once a week 40 miles round trip just to keep it from sitting.

    Used a Fram Ultra. This fill same thing went in but I added a quart of HPL engine cleaner to see what happens. Gonna change the filter every few thousand miles. Curious if the HPL would do anything to the consumption. I got a work car so this is being driven a lot less, it’s just turned into my...

    2012 Buick LaCrosse 6T70 30k mi OCI Amsoil Signature Series

    Yes it is ATL. The entire fluid change history is on the report. This is the first time that I didn’t do a 3x drain and fill. Only ever sampled the first drain every time. This time I only did 1 drain and fill. Was planning on every 20k repeating the process

    2015 Tacoma 4.0L 1GR-FE Amsoil SS 0w-30 31.6k mi OCI

    Probably hard to remember on a forum like this, but just the average car owner. Even better because he wants a UOA. We went 25 without burning a single drop. Not crazy to think 31 wouldn’t be missing any either.
