What oil do you use?

Using Pennzoil Platinum Euro LX 0W30 since I bought a stash last time it was on sale. Figured the 0W would be good for our -40C winters.
 
Costco now has 2 5qt jugs fully synthetic 5w-30 for $24.

Internet basicly shows Amazon, walmart,costco...all made by same company. Its pretty cool stuff.

I go around 8k miles per change jut because its only $12 per change but would not be afraid to go more. I have 250k miles now and she is running good.(I purchased at 145k 10 years ago.
 
5w-30 Mobile 1 + BG MOA. Ya know, it's over kill with the BG.
After reading the results on some members on here who has going through Blackstone labs and graciously shared the results, it's usually not about the oil. Most results came back more mileage can be safely added to the existing oil change. Of course, the health of the engine comes into play. How good are your piston rings, valve guides, bearings, etc.
About to make the switch to Costco synthetic 5w-30.
 
Project Farm on YouTube did some oil testing and it was a great set of videos.

I have no clue what he does for a living but his videos are very good IMO and so far all are useful in making decisions.

Max life 10w-30 full synthetic. Have also used Liqui Moly Motor Oil Saver every other year in the crankcase. Probably the best oil I have used since ownership in 2006 was Pennzoil Ultra in 10w-30. Averaging about 3000 miles a year now.

That oil was/is awesome. The grey bottle right? Stopped using for the same reason too.
 
I get a couple cases of 6quarts 5w-30 Mobil1 full synthetic from Costco every time it's on sale for the 3 cars in our family.

I did see recently they are selling Kirkland brands now. That might be a little cheaper without needing stuff to be on sale but I'm wondering if they're as good as Mobil1
 
19963.4lsr5 made a good read/link above. You should check it out.
The Amazon Basics oil seems to be on the same level a Mobil 1.
Costco synthetic and Walmart synthetic oil seems to be almost the same.

I’ve been using the Pennzoil platinum and Ultra for years.

My fall back is Motorcraft 5w-30 or Rotella T5

That is correct. Trying to find Ultra these days is all but impossible.

I am using Shell Rotella Gas Truck oil in my sister’s 2013 4Runner with great results. Maybe a tad too thin for the 5vz but YMMV :bathbaby:

My local Walmart has the Ultra on the shelf 90% of the time.

I've been using Mobile 1 coming up on 100k miles now with toyota oil filters. I'm at 308K miles now. I noticed the whole lubed area of the head was covered in an even varnish when I did my VCG back 65K miles ago. No sludge, just gold color varnish. My oil change interval is at 5K.
Would Pennzoil Ultra Platinum keep it cleaner than Mobile 1 did?

There's a 5W30 version of that.

You could always pull the passenger side VC and take a picture and then run the ultra for a few years and compare. I doubt the Ultra would get rid of the varnish.

After watching his videos I am really thinking of switching to the Supertech as a fall back oil instead of the Motorcraft. I do use their synthetic gear oil already.
