Suddenly burning oil
Hey guys, so I have a scary issue that I just noticed. I bought the car with 75k, changed oil the first day I bought it with some basic valvoline full synthetic. Car was almost completely stock, and it didnt consume a drop of oil for that first 3k mile interval. Then I went bolt ons + e85, and decided to run brad penn 10W30. I'm about 1500 miles into this oil change, and I'm more than half a quart low already. Wondering what's going on. Any input? Could it be burning since it's a partial synthetic? Thanks guys

I wouldnt be too concerned. Maybe you slightly short filled your oil & after it soaked the filter you ended up showing a low reading (just a thought)

Same thought here as well. My setup is stock motor & been running E85 for many years. After my latest tune, my shop installed 15W/50 which is great for high heat cycled engines (high ambient)

Could just be that oil.
Also, 1/2 quart in 1500 miles is NOT bad. You also recently increased power levels (at what seems like the same time you switched oils). The increased power can (and usually does) accelerate oil consumption.

Rule of thumb I was given many years ago is if the motor had always run conventional, you can switch to synthetic with no problems. If you have a motor that's always been run on synthetic, but then try to run it with conventional, you will likely experience problems. I don't know how accurate that is, but that's what one of my auto teachers told me many, many moons ago.

I was curious about that so I did a quick google search and found this. https://www.popularmechanics.com/car...a1497/4213451/
TLDR: It sounds like it was somewhat correct info back in the day, but nowadays it is incorrect.

I found a jug of oil at Walmart labeled "exclusively for Mercedes", put it in my Subaru and I had to add oil before the next oil change - 3K. Switched back to Walmart junk oil and no oil consumption.
