Engine oil Mobil or PENNZOIL

Mobile one full synthetic hands-down. I have a 2004 Toyota Corolla and a 2007 Toyota Tacoma I’ve owned both since brand new and now both have over 260,000 miles apiece . I have only used Mobil one full synthetic changed every 5000 miles. just took a bore scope to look into both engines a few months ago. They look like they’re brand new. Almost no varnish. Absolutely no sledge, never had any problems whatsoever with these vehicles. It’s insane.

my vehicles use only Mobil 1 oil.

I usually buy Pennzoil, it's inexpensive and it works. I check the contents first to make sure the oil isn't full of gunk in case someone swapped it. I do oil change every 5k km, which is once every 2-3 months, hence I don't worry much about too much gunk as I flush it out often.

I have used Motul and Castrol before and I found the Mobil oil to perform and keep the engine cooler and smoother on my triumph.

Mobil 5w-40 or Liquimoly. 10w-60 for hot summer track days.

I use the Penzoil Platinum Euro LX Full Synthetic 0W-30. No issues past 2 oil changes.

Mobil 1 AFE 0W-30 is what they used at the dealership and I’ve read a bunch of other people use it. I use it. Supposedly better than the mopar one.

The oil for our car is VW 504.00/ VW507.00 the 504 spec is 0W/30 and the 507 is 5W/30 only difference is fuel economy and the 5W/30 is the better choice i have used Penzoil Euro Lx for 0W/30 and oil does get by rings so might see puff of smoke on initial start, but with the 5W/30 Total nothing.

Throughout the summer I was averaging a quart every 750-1000 miles, still using Mobil1 15w50 & Viscoplus. This winter it dropped back down to 1 quart every 500 miles, but as the weather has warmed up, my consumption seems to have decreased again. I think that had something to do with the oil, which was admittedly way too thick for cold weather. I would let the car warm up a couple minutes before driving because that oil is syrup in cold weather.

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.
