I get penzoil platinum full synthetic 5-20 on amazon for 19.99 5 quart jug...high mileage for my 2009 f150 that has 230,000 miles and regular for my 2001 f250 that has 50,000 miles..

I buy oil from Costco when it's on sale . 5 quart jugs in boxes . About $3.15 a quart for synthetic

I've even had boxes of oil shipped to my door for free . Not sure how that pencils out for them

Partial stash

Looks like the regular price for Kirkland full synthetic is $20/5 qt jug shipped to my door free just like you said! I’m gonna have to keep an eye out for the sale and order several changes worth. Even that regular price is about as good as you’ll find anywhere for synthetic. Happy trapping! ScottW

I don't even have a Costco membership a co-worker does , as do some friends and family

when the oil sale comes around my co-worker is always watching for oil , I start shelling out 20s to cover the cost he has it shipped to my door.

I need some more 5w20 next time the sale rolls around

it was $32.xx for 10 quarts last time I ordered. that was shipped.

Napa has a sale on Mobile Delvac

FWIW,
You can find the parts cheaper on Amazon.

That's Cool

250 or 400 is cheaper than a toasted engine

The free oil change on my last truck they forgot or did not tighten a skid plate bolt it took a bit to figure it out. The oil change guy in many garages is the bottom of the totem pole entry level position. I worked at a Lincoln dealer many years ago the kid put brake fluid in the master cylinder and ruined the rubbers on the brake hydraulics.

He said, “ all hydronic fluid is the same” just before he was fired.

Friend of mine had his motor runt geting the oil changed at Walmart years ago. I don't remember the details .

if you pay any place to change your oil have the brain enough to check the blasted oil!! folks have forgotten what dipsticks are used for. my father yrs ago had his oil changed at a 15min shop then drove 3 hrs to my house an said it smells hot ...wasn't enough oil to reach the dipstick. $$$. take 1 min of your time before you leave the shop an prove they actually did their job. or be a real man an change it yourself with not OEM filters

About 30 years ago my mom was moving from Washington to Virginia. Before she drove across the Country she had her oil changed at Firestone.
On her way down Lolo Pass from Idaho into Montana her car engine siezed up. The tow truck drive said her oil drain plug was missing.
Firestone put her up in a motel for a couple of days, flew her to Virginia, paid to ship her belonings to Virginia, put a new engine in her car in Missoula then shipped her car to her. They even paid for her rental car for a few weeks in Virginia.
Glad I wasn't that guy who changed her oil

I order oem Cummins filters from Walmart online, it costs me about $200 with oil to do my 6.7

I used to be a "real man", now I let other "real men" change it.... geeze....

I changed oil in my John Deere GX345's as I have two of them. It was cheaper to go to John Deere and buy oil and filters, both air and oil. Cheaper than I could buy on Amazon. With exact same oil and filters.

Synthetic Rotella 15-40w was $22 a gallon at Menards. Rotella non-synthetic is $35 for 2.5 gallons. Parts store is about the last place to buy oil !

I've been buying 5 gallon buckets of rotella 15-40 at Walmart for 69$.
