oil change interval

cman227 · 06-19-2020, 05:10 PM

So with the whole lockdown thing, I haven't been driving the Z very much. It's been 10 months since the oil was changed but I only have about 1500 miles on this oil. I have heard various people say you can push an oil change out to a year but I have also heard engine oil breaks down over time. Does anyone out there have a Z that they don't put much miles on and stretch the oil change interval past the recommended 6 months?

I change my own oil/filter once a year. I only put on less than 2K miles a year on average, though.

Same here. I use synthetic and change my oil once a year prior to winter storage. I only put about 3k Kms a year on mine.

PS: Every oil will eventually have its constituents break down and separate over time in storage. But we are talking over a decade, not months. A lot of luxury brands have already gone to 1 year oil changes. Nissan is one of the last remaining manufacturers requiring 6-month oil changes.

Every 3k miles. Even if it's synthetic it's been sitting in the earth for a billion years, it ain't gonna break down if you leave in an engine for a year.

I change every 4,000 miles. I put less then 4,000 on a year. So every winter, I change oil.

Oil does break down sitting in a bottle on the shelf. Ever open up a bottle and have chunks come out.

I had a couple bottles of Castrol 4 Stroke Racing oil for the motorcycle sitting on the shelf behind a few things. Forgot all about those bottles for a couple of years. Out of sight, out of mind. Decided to start to ride the bike more, and it needed an oil change. Drain the oil and changed the oil filter. Opened up the first bottle and it poured ok. The 2nd, 3rd, and 4th bottles each had chunks of oil come out. Drain all of that out and got 5 qts of fresh Mobil1 bike oil. Couldn't get that type of Castrol oil anymore.

That's a great argument for not buying Zoren-style 4 Stroke and Done racing oil.

Amsoil top of the line. 1 time a year. I doubt I even put 1k on it in a year?

I use Euro spec 0w-40 Abiotic Oil in all gas engines. In the diesel, I use the Diesel spec Abiotic Oil. The best there is.

Is an oil change every 6 months really that much of a hassle? If you can't be bothered enough to do an oil change more than once a year, I'm guessing you don't have time to drive the car either, which begs the question, why do you even have it...

When you have 5 vehicles to keep up, yeah.

Bike - 4 quarts.

Grand Cherokee - 6 quarts.

Z - 6 quarts.

Power Wagon - 7 quarts.

Motorhome - 5 gallons. YES...GALLONS.

That's a lot of oil in a year. 10 gallons and 3 quarts for one oil change for my fleet.

I've never heard you complain about oil changes lol

Better than replacing the fan blade on your motorhome

And which one of those vehicles do you drive less than 1K miles in a year? My guess is none

I was just asking the question to try and understand. I'm not about to sit here and judge someone's choices for their toys. To each their own
