About this episode

A fast Q&A session tackles reliability, oil-change habits, and expensive A/C failures. Nile “Motormouth” Jenkins argues that today’s tighter engine tolerances and thinner oils are contributing to early powertrain failures, especially in certain GM and other modern designs, and pushes the idea that 10–15-year-old, well-kept cars can be more dependable than new “plastic” builds. He recommends changing oil early (even with synthetic) and never cheaping out on filters. For A/C, he warns that letting it sit dead for months can contaminate the system, driving repair costs up—often requiring an accumulator and flushing.

Technical Too Afraid to Ask
Concept

value for your money

"...was that better technology and better value for your money then or now and my answer is the stuff I'm seeing in the mechanical failures..."

They’re talking about whether what you pay actually gets you a car that lasts. If the car breaks a lot, it’s not really good value even if it looks good or is new.

Concept

price does not reflect the quality of the goods sold

"[948.7s] be thicker by at least a millimeter at least yeah price does not reflect the [957.1s] quality of the goods sold I saw that in a hardware store many years ago"

They’re basically saying the price you pay doesn’t always mean the product is better. The speaker argues that modern stuff can cost more while being made with worse materials or workmanship.

Concept

out of warranty

"there's no way I would want to be on a hook for a second or third engine and I'm out of warranty"

Out of warranty means the free repair coverage has ended. If something big breaks—like an engine—you usually have to pay the bill yourself.

Term

wear and tear

"exactly what you said the tick is gone I said well let's hope the wear and tear isn't too bad and that it can it can rise to the to the cause you know and last for a while quite a while okay"

Wear and tear is just the normal aging of parts as you drive. Regular maintenance can slow it down, but if something is already worn, it may still need repair.

Term

spark plugs

"when you're looking to buy a vehicle maintenance free all you don't have to change the spark plugs for 225,000 kilometers this that and the other thing"

Spark plugs help the engine start by creating a spark. Even if a car is advertised as “maintenance-free,” spark plugs usually still need to be replaced after a certain mileage or time.

Concept

reliability research (Consumer Reports, blogs)

"I'd be on top of consumers reports reading blogs and I mean you got to spin a filter on when you read blogs"

They’re talking about doing research before buying—like using Consumer Reports and reading online posts. The goal is to learn what tends to go wrong and what owners report.

Concept

count on for reliability

"...time and energy to put together a top 10 list of vehicles that you could count on for reliability..."

“Count on for reliability” suggests the speaker is emphasizing predictable ownership—cars that are less likely to require frequent repairs. This is a key filter when comparing vehicles beyond just performance or styling.

Concept

dealbreakers

"...they can generally rattle off three to five things that are dealbreakers for them so... put a line across the middle top half things I like bottom half deal breakers that's the things that you know what I just I cannot accept... so that vehicle's gone..."

A “dealbreaker” is something about a car that you just can’t accept. If the car has that problem, you move on—even if it’s otherwise a good deal.

Concept

road test

"I like it I will put it on my list if I don't like it you won't see my face again I'm not here to talk numbers be square with them I'm here to look at it and a little road test around the block and see how it feels"

A road test is just a short drive to see if the car feels good to you. You’re checking things like comfort and how it drives, not just looking at it in the showroom.

Concept

goals vs what you can afford

"you think you know what you want and when you start looking at what you want versus what you can afford you've then got to make some changes right"

This is about realizing your dream car might cost more than you can spend. You may need to change what you’re looking for or accept certain compromises to make it work.

Car

1998 Honda CRV

"...I think it was 66,000 miles when I got it 98 1998 Honda CRV I sold that thing and it's still going..."

They’re talking about a 1998 Honda CR-V. It’s an older Honda SUV that they drove for a long time, showing how some cars can last a lot of miles if they’re cared for.

Concept

automatic transmission oil

"...when I went to get some automatic transmission oil for the CVT transmission..."

They’re talking about the fluid inside an automatic transmission. Using the right fluid matters because it helps the transmission work correctly and last longer.

Term

CVTs

"doing I go yeah I said these CVTs you got to be good with them you got to be gentle on them you got a care give to them but I think they can go the distance"

CVT means “continuously variable transmission.” It’s a type of automatic that changes smoothly instead of shifting gears, but it needs the right fluid and regular service to last.

Term

factory fluid

"if you're changing the fluid with the factory fluid every 50k and he goes be nice"

“Factory fluid” is the exact type of fluid the car maker says to use. Using the wrong fluid can make the transmission act weird and wear out faster.

Concept

pattern failures

"and then I got a piece of junk that's always got the same pattern failures on it no it's my money and I'm spending it wisely"

They mean the same kind of problem keeps happening to that car. If a model has a known repeat issue, it can get expensive even if you try to maintain it.

Car

Nissan Rogue

"Nissan Rogue I've never owned a Nissan I'm kind of really liking it so far it really is good on fuel incredible on fuel"

The Nissan Rogue is a common SUV that many people use as a daily driver. The host is saying it can be really good on gas, but you still have to treat it and maintain it the right way.

Term

rustproof

"mechanicals rustproof number one guess what winter winter chicken dinner period"

Rustproofing helps protect the car from rust, especially if you drive in salty winter roads. It can help the body and undercarriage last longer.

Brand

BMW

"...if you buy one you buy a beamer or Mercedes or a Volvo or an Audi or Volkswagen..."

BMW is a European brand, and the point here is that it often needs specialists for repairs and maintenance. That can mean higher costs than many U.S. cars.

Brand

Volkswagen

"...Audi or Volkswagen anything like that don't expect your domestic automotive service tech to be able to work on that..."

Volkswagen is another European brand they’re grouping in. The takeaway is that you may need a specialist shop rather than a generic domestic mechanic.

Brand

Audi

"...a beamer or Mercedes or a Volvo or an Audi or Volkswagen... get out of that pipe dream that you're going to buy an Audi and treat it like a Chevy Trax..."

Audi is used as an example of a European brand. They’re warning that you can’t assume the same repair experience or costs as a typical U.S. car.

Concept

apples to oranges

"those vehicles and have a domestic tech work on it again it's apples to oranges and those vehicles they really like the same name brand parts Toyota on Toyota"

It means “these two things aren’t really the same.” So you shouldn’t compare them like they’ll give the same results.

Brand

Toyota

"and those vehicles they really like the same name brand parts Toyota on Toyota Honda on Honda Nissan on Nissan etc that's the way they run the best absolutely"

Toyota is the car brand being used as an example. The point is that using the right parts and systems for that brand can help the car last longer.

Concept

aftermarket parts

"there are some things you can certainly put on aftermarket that would be just fine like brakes tires etc suspension and steering when you get into the electronics"

Aftermarket parts are replacements made by other brands. The idea here is that some are safe to use, but electronics can be more problematic if they don’t match the car well.

Concept

maintenance

"because now you're talking a whole new breed of animal if you didn't like doing maintenance on a gas jobby you are certainly not gonna like a diesel"

Maintenance is the regular work you have to do to keep a car running well. The speaker is saying if you don’t like doing that for a gas car, diesel may be even more frustrating.

Term

engine oil

"...asks how often should I check and change my cars engine oil I'm [using synthetic] well I'm gonna tell you what I do..."

Engine oil is what keeps the engine from grinding itself to death. Changing it regularly helps the engine last longer and run better.

Term

oil change

"...I changed my oil I probably I'm gonna say I do put out better oil than what most have in their automobile in fact the oil change I did this week..."

An oil change replaces used, contaminated oil with fresh oil to restore lubrication and cleaning capability. The interval matters because oil degrades and collects contaminants over time.

Term

engine block

"...it's acidic it's cheap compared to that engine block in there any day of the week extending oil change services..."

The engine block is the big main part of the engine. Keeping oil clean helps protect it from wear and damage.

Company

Wix

"[3561.7s] less every filter I buy is a Wix filter I've done that since the early 70s they haven't let me down yet"

Wix makes replacement filters for your car. The point here is that the host trusts Wix because they believe the filter quality helps protect the engine and other systems.

Concept

full synthetic

"they dissipate a lot of heat but for the average Joe average Joe they're not going to see the feature benefits out of running a full synthetic"

Full synthetic means the oil is made completely from synthetic base oils. It can be better for heat, but the big advantages may not matter as much for everyday driving.

Concept

A/C leak

"no it fell out well possibly there's a leak well if there's a leak that means the refrigerant leaked out"

An A/C leak means refrigerant is escaping somewhere in the system. Usually you have to find and fix the leak, not just add refrigerant.
