HM Oil Thoughts

[Zee09]

Valvoline starts off with...……………

Engines change with age. After 75,000, treat unseen issues to maximize the life of your engine.

Shouldn't they say, "Engines change with miles" ?


Seriously, age does the same as miles-correct?

You may need HM oil for a 12 year old car that has just 30K miles on it.

Food for thought

 

[Zee09]

I remember seeing a two year old car at the dealer
It had 92K miles on it.
Looked new and of course the dealer said they were easy miles.
Salesperson interstate use...…….
I guess its HM oil time too

XOM says you can use HM oil for your first oil change!

I'd much rather buy a 2-year old vehicle with 90k on it than a 9-year old vehicle with 2k on it. There are many things on a vehicle that degrade without usage, and generally a high-mileage young vehicle receives the proper care and feeding because it is used as a work vehicle... perfect example of my latter reference:

My grandma bought a 1991 Lumina brand new, and stored it in a garage its entire life. She had the oil changed once a year. She passed in 2008 and left the car to my younger brother, who is a mechanic. The car had 3,447 miles on it in 17 years. While it looked new inside and out, the injectors were failing, the manifold gaskets were leaking, the brake lines were rusted and calipers frozen, tires were dry-rotted, the oil pan had drip-leaks, rear main seal was going out, window regulators and door lock solenoids didn't work, the transmission had sticky solenoids, and many other mechanical issues. My brother sold it untouched for $1000 knowing he was many thousands ahead rather than fixing any of the issues.

So yes, as Mola and other tribologists have stated, you can use HM oil in a brand new vehicle with no detrimental effects.

For me it's about formulation. I can get a 30W with a higher KV@100C and higher HTHS. A3/A5 vs ILSAC. Works better in my old junks. Also noticed it fixed dripping seals.

A sitting car and a vacant house have much in common

Oxygen ages/degrades many materials.

Are there any HM d1g2 oils other than valvoline maxlife syn?

They should say marketing works.

It really depends on how those ultra low miles were put on. My last 2 daily drivers were 5 and 7 yrs old when I bought them with 29K and 22K miles each. That was enough mileage to ensure there was little wrong with them. I had generally trouble free mileage with both of them for 7 yrs each after they had racked up a combined 315K miles on the pair. Minimal leaks on all the fluid systems. I rolled the dice for a 3rd time on the same type of car in May of this year.....39K miles and 17 years old. Not a single leak so far.

I know a couple of collectors with very low mileage 20 year old performance cars in which they only drive them 200-500 miles per year. In many cases they report no leaks and running just fine. My own 1999 Camaro SS was bought from the original owner w/12K miles when it was 12 yrs old...and it sat idle a lot the last 5 yrs of their ownership. Now at 18 yrs old, 19K miles...and still zero leaks. Runs like a top. Only items that have failed along the way are power window motors and one door speaker. It gets out every 2-4 weeks weather permitting.

Whatever they claim might be marketing, but they aren't wrong when saying age. A 25 year old car, low or high mileage, is not in the same shape as a 1 year car. It's all logic. However, mileage aside, you should always take a car you are considering to buy to a mechanic.

 

[KCJeep]

I have long believed the 75k rhetoric was simply marketing and a number pulled out of thin air for the purpose. I do like HM oil and will use them whenever I see fit, but the 75k thing is total bunk. It seems that ever since Valvoline started it though, every HM oil has followed the with the same line.

If you look at voas,hm oils usually have more moly and a higher tbn.

Your sig indicates otherwise

 

[dave1251]

HM tend to have a bit more additives, thicker, and a tend to slow consumption.

 

[SevenBizzos]

I think at 75k things are just getting settled in. I wouldn't consider a car "high mileage" until double that.

Oil companies just needed a number to put on the bottle as a reference point. Consumers are funny that way. It varies widely engine by engine. I would certainly consider a BMW engine high mileage at 75k. At that point many seals/gaskets are already or close to leaking.

You said "tend" so I'm not correcting you, just wanted to add that PPHM is thinner than regular PP.

I've noticed that too,looking at the pds. PPHM is thinner than PP. It has at least twice the amount of moly that regular PP has via voa (thanks 53' Stude

).
