Thanks. Well, for now, burning 1 qt every 4000 miles is super acceptable to me, for an engine with 140k miles on it. If it lasts the kid through 4-5 years of college, at around 10k miles a year, it will be a success.

Why every 6 months? It has already been over 6 months on this example. I am hoping that using Valvoline Restore and Protect might be able to keep the oil control ring from getting carbon deposits and the problem returning. Only time will tell. If we have to perform this activity once a year...

It most definitely will not burn off to quickly, because one person did a hard drive with the chemtool in the crankcase, took it out on the highway, did several Italian tune-ups, and ended up developing a rod knock.

I dont think there is much need to do a short OCI with cheap oil. I did it mostly just in case there was any sludge from the flush, sill coming out.... and honestly $30 in oil/filter is just NOTHING compared to any real engine work.

Update: 12/20/24 - 139819 miles. 3959 miles since last oil change. This includes two highway trips around 1000 miles each. It consumed very close to 1 quart of oil (see picture). I did another oil change with Valvoline Restore and Protect 5W-30 and this one is going back to college after...

UPDATE: 11/25/2024 - 135389 miles. It has been driven 2529 miles since the piston soak and oil change. No oil has been added. It is currently right between the two marks on the dipstick (according to him), so around a half quart low. The way it was burning oil when it was purchased, it...

It's absolutely fine to drain it out (and probably the best advice). I just ran the engine for 5 minutes at idle with the Chemtool in it, to act as an engine flush to remove some sludge from the engine and crankcase. Berryman has this to say on using B12 in the crankcase: "Berryman B-12...

He still has not had to top up at all. Around town driving the consumption is very near zero. He checked it the other morning and after sitting all night, it was nearly to the upper line still. So it really hasn't even consumed 1/4th of a quart since we did the last oil change.

I might if I can. The vehicle is away off at college - and it likely won't be near the next OCI until next summer. I'll be interested to see how much oil gets consumed between now and then.

2006 Toyota RAV4 with 2.4L 2AZ-FE engine, purchased with 131,000 miles. This vehicle had a Carfax with documented oil changes (most at dealerships) every 5000-6000 miles for its entire life. It burns oil. A LOT of oil. 1 QT of oil every 300 miles on the highway at 75mph and 1 QT every ~600...
