Engine oil Mobil or OEM Toyota

I get my oil from Sams for about $60 for 4 gallons. I use the Mobile Delvac and haven’t had any issues.

Mobil 1 high mileage 5w30

But personally i like Mobil 1 brand

I went with Mobil 1 5w-30 ESP. I read around the Bob is the Oil guy and that is what I came up with what I would best for WRX that will be tuned with an intake (My opinion). I am sure there are other good options.

Other vehicles, I ruin normal Mobil 1 until about 80-100K miles and switch to high mileage. Put over 200K on a '04 Civic Si on all Mobil 1 and oil analysis came back great every time.

I used the mobil synth high mileage 5w-30 for years in a 2001 accord lx 4cyl with 200k thru 274k miles when i sold it. Changed it about every 4k

My Tiguan and Passat all function perfectly with Mobil1 5W40, and I have used this oil for 15 years.

I found a really good deal on M1 ESP 0w30, about half the price of the LM. ESP is a good choice for modern DI motors for it's low volatility base stock, less oil vapor in your intake and better for cats. ESP is as good as it gets imo.

I put Mobile1 0w-40 in mine, even though it's not vw certified

At my 18,000 mile service, barely dropped off full. V.W.they told me at the service has now went with Mobil 1.3,000 miles later down now a 1/2 quart.
