Thoughts on cheap oil?

If you really want to go down a rabbit hole, go visit Bob Is The Oil Guy

Crazy-technical forum full of oil geeks.

Bottom line - Kirkland (Costco), Super Tech (Walmart) and Amazon Basics full synthetics are all good to go.

Whenever my local Walmart has the 5w30 jugs in stock, I neckbeard at least 4 or 5.

The 99 is just about to turn over 300K - Been a great cheap car for her. Was just concerned with starting oil consumption if I went to synth.

I have seen Mobil 1 sell for less money than Amazon Basics full synthetic oil.

If my motor rattles on start up it's not good enough for my trucks. This is why ACDelco oil is used in ours.

Most of the oils out there have viscosity numbers that are quite low. ACDelco, the old Shell Rotella Gas Truck and RedLine have the highest numbers.

I only heard the rattling on the first start after the oil change but maybe it was one of my kids scooter or something. Since the oil change I've remote started with my head in the wheel well both cold and hot starts and no more sounds of concern, just the first time after changing the oil.

Looks like you can get quite a bit of kirkland oil for $75 so I might go that route in the future if its all good

As far as I know it's ok to move from conventional to full synthetic but you don't want to go the other way around. I have a buddy with a 67 impala and he is adamant about strictly using "dinosaur juice" (conventional) oil in the motor.

I had a 1996 Chevy Suburban that I bought in 1998 with very low mileage. I serviced the vehicle myself and owned it for 20 years. I traded it to a friend of mine with 600,000 miles on it and the engine runs perfectly and uses/leaks less than a quart of oil in 4000 mi. That vehicle never had anything in it except Walmart oil and Walmart oil filters. There are two basic types of oil: clean oil and dirty oil. If you change it frequently clean oil, regardless of brand, is excellent insurance for longevity.
