Engine oil

Hoffer1066 · Apr 12, 2022

I am well versed I guess you could say in maintaining my own vehicle. Have rebuilt everything from engines to trans, rear ends etc. Oil consumption in any engine to me is a little alarming and I don't consider it normal. It just seems these newer engines get cut a lot of slack for how good they should be designed. If I wanted to add oil between oil changes, I would have bought an 82 suburban or something.

V-8, no Ecoboost for me.

My wife's 2013 5.4 was ran on synthetic 0w20 synthetic for the first 50k of ownership because I had a drum of it. Now that's gone I have been using costco 5w30 synthetic. When I have towed at highway speeds a lot ot uses some oil. Maybe a quart every 5k. Normally not enough to add between changes. Were at about 100k now, no problems, noises, or leaks.

I have a 2013 Limited and a 2014 Limited, both with the 5.4 engines and I change my oil every 5k miles. The 2013 is my wife's and I have the 2014. Her's is all stock and my has the leveling kit and cold air intake. The 2013 has 162,531 miles and the 2014 has 160,125 miles with no oil leaks and no issues at this writing. I take them into our local Ford dealer ship ( the shop is one of the best I have seen for a dealer ship) so the oil is 5w20 synthetic.

2 quarts in 5,000 miles is excessive, I change my oil every 5,000 miles and it only looses about 0.5 quarts. I run Walmart, O'Reilly, AutoZone, whatever 5w30, the oil weight these engines were designed for, and I'm at 170,000 miles. I would do a leak down test to make sure there's no problem with the rings, and if they're good it's probably valve seals. If it's not leaking on the ground, it's going out the exhaust.

Note: I had a customer swear he was having to add a quart after the first 1000 miles on an oil change. Ended up he was using oil in a bulk 1 gallon jug and thought it was 5 quarts (a gallon is only 4 quarts for those who don't know) and then only adding 1 quart. So he was filling only 5 of the 6 quarts required, then checking at the 1000 mile mark and it was 1 quart low. He was pretty embarrassed, but glad he didn't need a rebuild!

interesting how so many have the mentality of, oh i haven't had a problem yet so it's not a problem yet. I just don't get it - just do 3-4k oil changes, use the SAME oil every time, rather that's your cheap walmart oil or the good stuff, and then take a peak in the oil fill spout and see the condition of your valve train components like every 75k-100k miles. I don't get why people don't baby their vehicles, letting sludge and varnish build up and then a future owner has to pay the price when they buy your used vehicle that you beat up.

LOL!!!!! did he not check the dipstick? just fill and drive off? lmao. glad he learned his lesson, eventually.

Correct engine level is anywhere between the Full and Low marks. Anywhere between the marks. No reason to constantly bring the oil level up to Full or add oil unless at or below the Low mark.

Some engines will "burn" oil down to a point between these marks and then stop. Adding a half quart just starts that process all over again leading to the assumption the engine is burning much more oil than it would if left alone. Again this applies to "some" engines.

My oil sample analysis confirms that when using full synthetics mileage, not time, is the determinate in my engines. Unlike bread modern engine oil doesn't go bad just sitting there.

Mine uses more near an oil change. I run pennzoil ultra platinum 5w30 in the summer 5w20 in winter and always the ford oil filter.

I'm old so I remember when the manufacturer specified oil change at 5,000 miles. Then all of a sudden when the quick drive in oil changes came to be the interval for some unknown reason was reduced to 3,000 miles. Why do you think that was done? Did the oil all of a sudden degrade? Or did Penske and all the rest come up with a new way to make money.
