Mileage or Time?

[JennyPenny90]

Ok. I am pretty sure this question has been asked before.. So please help me with links or advise.

If a car is driven daily for around 10 miles. Tropical weather (around 24-34 degrees Celsius). Traffic is smooth and engine gets to operating temperature (usually it takes 15 mins)

Should I follow the time interval (ie 6 months) or should I follow the mileage (ie 10,000 miles)? I am doing approximately 3,650 miles yearly.

I am running Euro Pennzoil 5w40. As this is cheap and readily available.

Thanks!

Engine is 4GR-FSE. Mileage so far ~30,000 miles. Fuel of choice, premium Shell V power

I would change every 18 months.

Driving only 10 miles per day, I would change it once per year.

I like the 18 months idea. If the oil is that cheap and if you love the car then maybe 12 months. You can even go 2 years (I would) ... That's why I liked the 18 months idea!
That oil is too good for 6 months (1825 miles).

Yearly

Ignore the time duration (of 6 months or 1 yr), as your minimum 24C is considered 'hot' by many a guy.
7500 miles may be reasonable for an Euro 5W40 in your context.

I gave up on time [to keep the warranty people happy] and base it on mileage. If I were to go by time with my van I'd be dropping oil with less than 2K miles on it once a year. My Rubicon would be getting the oil dropped with 3K miles or less. I shoot for 4K miles in the van now, and 5K in the Rubicon.

Yea, every 2 years...

 

[tiger862]

I'd do 5k.

 

[Nickdfresh]

I'd do it every 18-months. My father barely has 2,000 miles on his car and I am going to change it at the 18 mo.mark...

 

[zzyzzx]

I would do it based on mileage, but more like 7500 miles, not 10000.

Twice a year, your car will appreciate it later in life.

Agreed.

Oil does not know time. 18 months (aforementioned) is a great idea! Are you able to get Used Oil Analysis? Make sure you use a good air filter and a good oil filter.

I would not go beyond 5 months better yet every 3 months if you want to keep the car for a long time. It's not the oil that is the problem, but the condensation in the engine that turns into water and you must reach operating temp and keep it there for at least 30 min for this condensation to evaporate.

 

[OilUzer]

3 months / 912 miles ?

You must really love your car

op said the car gets to operating temps!

Facts please. I had OLDSMOBILE that got very little mileage with most being less than 2 miles and changed oil between 3 and 4k. Wish I would've taken pictures as I put 40k on it and you could still read casting numbers on the iron Duke 2.5 with Maxlife. 2006 Saturn Vue 5k oil changes on a dirty Ecotec with Pennzoil Platinum Dexos1 got 50k on it. Both vehicles were purchased used and at times go 18 months between changes. The dirty engines are caused by engine components that fail or forgetting to change before all additives are used up. With newer cars thermostats take longer to open therefore engine heats faster and moisture will not be an issue. I have never went by time always mileage and never had an engine fail from an oil related event, well one and that was oil pump in a 300k 1967 Chrysler.
40 years keeping my vehicles going

24 months is not pushing the limits of ANYTHING at 3,600 miles a year.

Get a tbn done on your used oil. That'll give you some idea of what your conditions are doing to your oil (both sitting and being run) so you can adjust your intervals accordingly.

 

[Skippy722]

I do almost the same exact drive cycles as you. I changed mine in February 2018 with Mobil 1 Extended Performance with 90k on it. I'm currently at 94,296. I'm running it to 5,000 miles and going to change it and send out a sample. Weather ranges from 100+ summer to below 0F winter here.

Some say I should just use the cheapest oil and I'll be fine when I posted a simile question, but the Mobil 1 Extended Performance was the same price as all the rest of the synthetics when I bought it so why not use it? I'll pay a bit more to know I'm good for 3x the distance.
