    Petarmor Flea Prevention

    Crazy good flea prevention deals this weekend, specifically large breed 3 packs of petarmor. Not oil related but we all have pets!!! Linking Amazon but chewy and Petco also have similar deals. https://a.co/d/1U7NYBr

    Never Change Oil - Delvac Challenge

    No changes in fuel economy or butt dyno. To this point for all intents and purposes it's business as usual.

    Never Change Oil - Delvac Challenge

    Haven't been driving as much lately so I went ahead and topped off at the 2500 mile mark. At 252,500 miles now, oil not changed in ~20,900 miles. Took a little less than a half quart to top off, otherwise everything still going fine

    Never Change Oil - Delvac Challenge

    Thanks! I honestly don't think I'm destroying the vehicle. This experiment should continue longer than some are thinking. Next filter change I'll try and capture enough oil to send off to Blackstone. That'll be ~3 years and 28,000 plus miles since the last time the drain plug was removed...

    Never Change Oil - Delvac Challenge

    It's an approved viscosity in the owner's manuals of gen 2s everywhere except in the US, despite having the same engine. I've been using 5w40 for years cause it quieted down a little piston slap the old girl has. Chose the delvac 1 for no real reason other than I already had 5 gallons in the garage.

    Never Change Oil - Delvac Challenge

    250k mile mark, changed filter and topped off with 1 quart, 8 Sep 2023. Miles since last oil change ~18,400. Will only top off with oil until 260k mile filter change. The challenge continues.

    Never Change Oil - Delvac Challenge

    Quick update. Changed filter only and topped off oil at 240k on 23 Aug 22. Just rolled over 245k on 15 March 23, topped off oil (about 3/4 of a quart). Currently at 13,390 since last oil change. I realize some on here do 20k intervals on the regular so this journey has just begun.

    Never Change Oil - Delvac Challenge

    Change of plans. My mechanic friend took a look at the underside and says many of the bolts are already corroded over, future repairs will be difficult and pricey. It also goes all the way around the underside of the body panels but I just took a picture where it ate all the way through. The...

    Never Change Oil - Delvac Challenge

    I'm not intending to destroy the car per say but it has limited life left in it at this point. One way or another I figure it's got about 5 years tops. I suspect as others have said that it'll be the rust that does it before the drivetrain. That is the whole purpose of the experiment... if it...

    Never Change Oil - Delvac Challenge

    I 100% get that logic. I'm highly confident whether I kill it slowly like this or wait out the rust it'll be dead around the same time. This car has 5 years of serviceable life left in it tops. In the meantime I have a 40 mile round trip commute each day so I do enjoy the gas savings.

    Never Change Oil - Delvac Challenge

    I got a new Toyota factory battery put in in 2016, it's got about 60k miles on it now. I'm using this oil and filter combo cause it's what I have in my stash.

    Never Change Oil - Delvac Challenge

    I know I've seen old discussions regarding this but I'm not sure it's ever been executed. I have a 2006 Prius that's about to roll over 240k miles within the next month. This car is basically completed depreciated out, the paint is burnt off, and the undercarriage/body has a fair amount of rust...

    SHTF - Prepper - Oil Stash

    Similar answer for me except Delvac 1 5w40. 10k intervals on everything. Just keep the tractor topped off.
