Cheap Motor Oil Alert!

Post by TC6969 » Fri Mar 16, 2018 1:58 pm

I was just in the Sun City Center Home Depot and since I needed one, I decided to grab a quart of 10W30 while I was there.

Shell Clean engine formula 10W30 $2.94.

This was regular price, not a sale.

Rural King $ 1.79 when on sale , probably comes from the same bottling facility
In the days of the old west a 6 shooter was as common as cell phones are today and just annoying if they go off in a theater.

Most of it does.

Ashland Oil Co = Valvoline, and probably 100 other house brands like Autozone and NAPA.

With a minimal order (It used to be 500 cases), you could have Gunstock and Barrel oil with your logo and everything.

It's that time of the year. Turns out to be about $14 for 5 quarts at Walmart after taxes. Yes,they accept Walmart receipts. I've done this 3 or 4 times now. Limit 2 rebates, and the check arrives in about 3 weeks.

One way to save money on engine oil is not to change it so often.
Just for a test, I let one of our cars go as long as possible between changes.
Judging the oil in the engine from smell, feel and such, the car went to 7,000 miles before it needed changing.
Supposedly, the real reason for oil changes, at least from the oil makers, is the loss of additives.
But others in the know say that aspect is greatly exaggerated.
This particular car engine didn't suffer from going that long without a change.
The car is twelve years old, but with only 60k miles.
It ran perfectly before and afterwards.
But as a compromise, I do change the oil in our cars as soon as they start to show a little low on the dipstick, about 5,000 miles or so.
Just a thought.

When Mobil 1 came out, it said good for 25,000 miles on the can. The company said nothing has changed and has actually gotten better, but they took it off the label because dumb people didn't check and top it off. I run it for 15,000 in my Chevy V8, change the filter and lube the ball joints and steering stuff at 7500. But people go 25k and the oil test comes back fine. In Europe, the standard is at least 10k miles on an oil change.

P.S.
As an afterthought, My four year old van has gone the entire time without an oil change.
It only has 3K miles, (guess I didn't really need it) but there's been no deterioration of the oil in over four years.
If the additives somehow disappeared, wouldn't it somehow show?
As far as I can tell, the engine oil is still like brand new.

After 2 years of just sitting on the shelf, the quality of the ingredients starts to degrade significantly. I would definitely change it, especially if it's a factory fill.

Changed oil on my 2 cars yesterday, plus my son's. Between us both it should save $51 - Thanks!

What about the 2 MILLION years it sat in the ground?

Your oil will outlast your filter. Not sure it it’s still the case but you used to be able to send test samples to amsoil and they would tell you how much longer you could run it, with a filter change of course.

Like the additives in gasoline, they start to break down after sitting for a while.

From http://upmpg.com/lubricationnews/why_mo ... eriorates/
High quality additives perform best and last longer when paired with high quality synthetic base oils.

Yes... The first additive to fail is normally the viscocity additive. You can test the viscocity of your oil fairly easily at home. There are kits available for that.

The next additive to fail is normally the dispersal additive and a simple card test will reveal if that additive is still good. The problem there is, if the dispersal additive fails, your oil filter immediately clogs up completely and the bypass valve opens so your oil continues to circulate without being filtered. Once that happens you need to do several quick oil and filter changes to clean out your oil passages again. If you don't, it doesn't take long for the clumped soot to harden in the passages and seriously reduce your oil flow.
