I guilt tripped myself into an oil change.

[Winger Ed.]

Back in the early 70s- Mobile spent a pile of money researching it before it went on the market.
They'd sponsor fleet vehicles and Police cars to run it until the engine blew up.
They'd pay 'em for a new crate motor to be swapped, and to send the blown engine back to their labs.

Most synthetic oil technologies were developed when ceramic engines were being experimented with. No cooling system. I can't remember what the operating temperatures were but it was WAY up there.

They never did find an oil that would survive.

[Winger Ed.]

I'd forgotten about that.
I remember on car company that built a few engines that didn't have any metal in them.
I guess they didn't work out.

I would have thought the oils used in high-temp. jet turbine engines would have worked, but I guess not.
I think they might have been soy bean based. I remember hearing some of the turbine engine oils
were so expensive they cost over $30. a quart back in the late 50s.

I use quality name brand synthetic oil and change it by the oil life monitor in the car. The old 88 Ford diesel and 87 Ford f250 460 change themselves but I still change them once a year. I try to change trans fluid or service changes anyway every other year or 30k miles. I guess anyone could send off some oil samples to be tested and then one would know for sure.

absolutly NO reason to change oil at 3,000miles!!

Jet engines use roller bearings while internal combustion engines use a type of friction bearings. I knew a guy who liberated some synthetic oil for use in jet engines and tried it in his pickup. Sized after roughly 10 minutes. Completely different lubrication requirements.

Our newest diesel tractor recommends a 500 hour oil change interval, compared to a vehicle at 75 mph that would be 37,500 miles! To me that seems excessive, so we still change at around 150 hours. I try to do the vehicles at 4-5K when using synthetic oil, but I agree that oil changes are cheap maintenance if done yourself.

[Recycled bullet]

I like to wipe the dipstick on a clean white paper towel ...it'll be obvious if the oil is dirty... Look at it, smell it... change it if it stinks like gasoline or change it if it's dirty.

An old coworker used to send samples to Blackstone labs. I found it easier to get two 5 quart jugs of synthetic oil at Walmart about every 5 to 7,000 MI.

A common cause of engine mechanical failures is from lack of lubrication and metal parts like bearing and vvti bits overheating and galling- from not having enough oil in the engine causing low oil pressure.

The engine oil is pumped around and squirts from tiny ports in the head to wet the valve train parts and works it's ways down back to the oil pan and pickup....it's taking the heat away exactly the same way that when you pour lead into a bullet mold you're pouring heat into the mold.

I couldn't tell you how many kias and Hyundai's where I've pulled the valve cover off for an inspection due to loud tapping noise or a check engine light valve train codes, no oil on dipstick, and there's a solidifying black plasticized stinking goo completely covering the camshafts ...that used to be the engine oil.
The worst one I had seen had more than 50,000 miles and was on the original engine oil that it left the factory with
I get the shop vac to suck the trash out, and sometimes they get lucky change the oil replace parts of their damaged reassemble it and then it doesn't make noise anymore. Although that one with 50,000 needed an engine due to zero maintenance...

Older high compression ratio diesel engines need to be changed before 3,000 miles.

[Hannibal]

Older high compression ratio diesel engines need to be changed before 3,000 miles.

Curious. What was the compression ratio of older diesels compared to recent production?

A diesel is high compression by design.

I had the numb nutz at the local Jiffy Lube change the fuel filters on my 2017 F250 recently. They broke the filter housing under the gas tank. It cost me another $1K to have them replace it. Anyways they won't be working on that any more. Good on you for changing the oil early.

[justindad]

I had a truck that got about 2,000 miles a year. I used the expensive oil that could go 10k miles or 12 months. I changed the oil at about 9 months and the Fran oil filter was seized in place. I crushed the filter with the wrench. I had to stab a screw driver into the side of the filter and use the handle to loosen the filter.

The oil might last a long time, but the filter can seize in place.

[M-Tecs]

Lots of farm vehicles don't get used much. Some go years between oil changes. Never had an issue getting any of them off.

WHY AN OIL FILTER CAN GET STUCK
There can be several reasons that an oil filter gets stuck, even if you’re using the right-sized oil filter wrench to try loosening it. It could be because:

The oil filter was overtightened. It’s extremely common for both DIYers and repair shops to overtighten filters, creating excessive pressure on the threads and gasket surfaces.
The effects of heat and time. As you drive, the engine’s heat can cause the gasket material to harden or bond with the oil filter housing or the engine block.
Rust and corrosion. If there’s rust that forms on the oil filter’s threads or on the mounting base, the filter could seize to it.
The filter was cross–threaded. Improper alignment with the oil filter adapter can cause the filter to be nearly impossible to remove – much harder than it would’ve been to crank it on cross-threaded.
It’s deformed. If the oil filter has been damaged due to impact or your oil filter wrench has squashed the case, it can make it difficult to grip and unscrew without making it even worse.
The seal wasn’t lubricated. A dry oil filter seal can make it exponentially more difficult to remove the filter at the next oil change since it grips the metal adapter base firmly.

Yep, oil filters only need a wipe of clean oil and hand tighten. Never use a filter wrench on it to tighten. I started having the valvoline shop change my oil when. I bought my Mazda a couple of 3 years ago. I put about 12k on that car still. Usually been 4 or 5 1000 mile trips a year. I change every 7k miles never sooner. Synthetic on that one. My old f150 2005 has 226k and has never in 135k of those miles had the oil changed in less than 10k miles. Usually 15k. 3000 miles is just wasteful. Oil is NOT cheap any more. Why change in half the mileage. And transmission fluid? I have changed only one time on one vehicle 45 years ago. Never on this pickup, or my last f250 that had 200k on it when I sold it. Never a tranny problem

A friend in South Carolina, when I was stationed there in the late 80's and early 90's had a 1967 Dodge Coronet, with the 440 & sixpack. He'd bought it new, and changed the oil every time he filled the gas tank. Had just gone over a million miles on it when I left there in 1991. Engine was as tight as it was when he bought it, according to his report.

considering that car that probably only made a 150 miles on a tank of gas that means a 1000 oil changes to get it to a 150k in todays money thats 60k if you use synthetic. i cab buy 3 complete long blocks for my challenger for that money or a whole new car. if he did it every 2k id understand. we did that ourselves on high performance motors driven hard back in the day. if he did that every tank of gas for a million miles. factoring in inflation and cost of living he spent in todays money over 400k on oil changes. that money would buy you 3 like new 440 six pack cars today. Which by the way would not be a 67 coronet or any mopar till mid 69. only big blocks available in 67 were the 383, 440 4brl and the 426 hemi.

1 have 4 vehicles 2 are just used in the summer (challenger and 06 silverado) one is just winter (my wrangler) and my ram is used year round. the three seasonal ones get an oil change before being put up for the season. the rarely see more then 3k a year. wife drives the ram and has it changed when oil life reads under 30% which usually relates to around 4k. i use only synthetic and only wix or mopar (which are wix) filters.

[Cast10]

My last truck, 2015 2500HD 6.6 DMax LML w/ Allison 6 spd. Just sold to a buddy of mine, had 116,000 miles and has NEVER been to the shop. The best truck I’ve ever had!

I changed oil when GM told me to; via the DIC. I changed the Bud Light at or around 75K. No burnt smell and always red/clean. I had an Edge monitor and I really paid attention to readings such as temps. The trans temp was the same when I sold it as when it was new. Hated to get rid of it, but as I get older, I want simpler.

[farmerjim]

My 1995 chevy 2500 has 55,000 miles on it. After the first 2 years it had
40,000 miles on it ( I was building a house by myself and had to drive 60 miles every 2 or 3 days to get supplies). So in 26 more years it averages 577 miles a year. I do change the oil every 2 years and only use synthetic.

[Rapier]

Got trapped into the must do, maintenance circle or routine. Keep a log, vehicles every 3,000 miles with synthetic. Equipment evr 100 hours and at 400 all fluids. I change filters at every change. I do not mind the tractors and carts, but take the vehicles in for a full end to end check up.
Reason is simple, if I decide to got to Seattle Washington from FL, I expect to turn the key and go, then come back, at any time I feel the need.

I bought the 2018 GMC in 19, it had 23k on it, now has 32k on it and is garage kept.

I covered three states as a special agent/investigator for the AIG insurance group. Did mostly bank, armored car, gambling establishment fraud and robberies and other such items. Put a lot of miles on a vehicle every year. Bought a new company vehicle every 35-38k miles. Could be a Chevy or Ford, neutral color, 4dr sedan, had national contracts with both. Came to prefer white Chevys, not the car, a better local dealer for future maintenance.

Mighty vac makes a tool for adding transmission oil it's a little pumper thing it works a lot better. I use it on Ford F-150 transfer cases and BMW transmissions it works fine.

I use a small hand pump I got from HF on my 5.4 Triton.
I also am in the "oil is cheap compared to an engine" camp. Put 5,000 yr on mine and still change it spring and fall. Both Hondas and the Fiat get 5,000 mile changes as it's easy to remember.
On my 2023 Freightliner the oil change is 60,000.
