Went to Costco today and was going to get a few cases of Mobil 1, but noticed Kirkland brand (Costco Brand) synthetic oils on sale from $24.99 - $3.00 sale, so total cost is $21.99. I bought a case of 0W-20 and 5W-30. Now Costco also had Mobil 1, 0W-20 and 5W-30 for $29.99.

QUANTITY:
KIRKLAND comes in a case with two bottles (5 quarts each) of oil making a total of 10 quarts per case.

COSTCO MOBIL 1 comes in a case of 6 one quart bottles.

WALMART MOBIL 1 comes in one bottle of 5 quarts.

PRICE: (your specific mileage may vary with prices)
KIRKLAND: Kirkland was on sale at $24.99 - $3.00 sale, so total cost is $21.99. I bought a case of 0W-20 and 5W-30. This comes out to $2.20 per quart.

COSTCO MOBIL 1: Costco also sells Mobil 1 in a case of six quart bottles for $29.95. This comes out to $4.99 per quart.

WALMART: Walmart sells Mobil 1 Advanced Full Synthetic for $22.38. That comes out to $4.48 per quart for their 5 quart jug.

Now, you are probably asking, is the Kirkland Full Synthetic any good?
Keep in mind that Consumer Reports doesn’t rank motor oil. About 10 years ago Consumer Reports said the brand was unimportant as long as it meets the requirements set out in the owner’s manual by the manufacturer. In today’s world of motor oils, I have to agree with that logic. The API (American Petroleum Institute) has an extensive sampling, testing and rating program. So if your oil has the API certification mark also known as the Starburst, you are using quality motor oil.

Is this the BEST oil for your vehicle?
In my mind, the BEST oil is the oil that meets all the specifications, viscosity, certifications, etc. set out by the manufacturer for your particular engine, with perhaps a little tweaking for environment. Or in another words, the best oil is the correct oil for your car.

What weights does it come in?
From what I could see on the shelf, 0W-20, 5W-20 and 5W-30.

Kirkland doesn’t own any oil refineries. Kirkland’s full synthetic is manufactured by Warren Distribution. They are one of the largest oil blenders in the country manufacturing for Walmart, Amazon and many others. The API oil ratings are the same for both Mobil 1 and Kirkland.

What oil does Acura recommend?
If you open your owner’s manual to page 437, Acura will state to use:
  • Genuine Acura Motor Oil (or)
  • Premium-grade 0W-20 detergent oil with an API Certification Seal on the container.
"Synthetic Oil: You may also use synthetic motor oil if it is labeled with the API Certification Seal and is the specified viscosity grade."

Having been a Mobil 1 user for all my cars for as long as I can remember, I see no reason why I should not change and start using Kirkland Full Synthetic.

At this price, I’m going back and picking up perhaps 5 or 6 more cases.

Amazon also has good oil. I still stick with Mobil 1 as I only change my oil once a year as I don’t drive much...I changed my oil in December and it still shows %100 life.

I fully understand, but when you have seen the numerous errors that oil change technicians do such as:
Overfill your oil level
Under fill your oil level
Leave oil cap off
Forget to check other fluid levels
Not tighten oil filter or use wrong oil filter
Get grease on paint, interior, steering wheel or other things
Steal money or other things from inside of your car
Using cheap oil when you paid for synthetic oil
Checking other things on car like air filter and interior filter and not fully closing the lid
Over or under torque the drain plug and possibly stripping the drain plug
Swapping your expensive magnetic Gold Plug drain plug with an OEM drain plug
Not to mention the oil change technician is normally the lowest trained guy in the dealership.
Etc, etc. etc. etc.

I won't even get into tire rotations.............

Yes, I have seen all these things done! Do it yourself (if you can) and know that it is done right!

Surely an Acura dealership would NEVER make those errors! LOL! I hear you, the first Acura dealership that I bought my TSX and first TLX from was pretty careless. Every time I picked my car up from service I'd have to do a careful 360 walk around to inspect for any damage. I had a '97 Nissan Maxima that a lady backed into when the car was only 3 months old. The dealer had a pretty good body shop and did a nice job fixing the dent in my front passenger quarter panel. Only problem was that when I went to pick up the car, I found a new dent and scrape in the rear bumper where a careless technician had backed it into a brick wall after doing an oil change.
