Pondering high milage....

[daves87rs]

Just watched the wife's car roll past 100k today...and for some reason, I suddenly feel the need to put some high mileage oil in it...

Quick background on the car: Had been using synthetic oil in this car (since 6k on the od back in 03) well before BITOG with M1. After BITOG, many different types of syns...

Engine is still very clean, but will burn a little oil when it gets cold out there..

A while back, the plan was to switch it at 75k...but I never did. I figure now at 12 years old and 100k, it might not hurt to switch to a high mileage syn like maxlife syn or M1 HM. Granted, I could just keep doing what I'm doing too..


Catch is the car will stay on a full syn diet, due do it being my wife's baby (she wants to run it into the ground) and the fact it does a bunch of city driving. Car is also getting more updates to keep her going strong...

Not hard to catch synpower high mileage on sale at meijer's either..

Her engine wont know the difference.

If anything, it'll likely prevent potential leaks.

Another alternative would be to get M1 and M1 HM and mix up your own desired amount of HM.

Go for it! There's certainly no harm in doing so. It just might slow that consumption down to where you won't have to do any top off.

What kind of car ?

100k is not much mileage for a high quality car.

My Saturn L300 at 119,600 miles still runs on Mobil 1 5w30 EP. Has been 11 months and about 7500 miles since the last oil change. Oil level just a tiny bit below full and oil is honey colored. I see no reason to go to an HM oil in your car at this point.

 

[Brybo86]

Keep up what you are doing unless it is burning a lot of oil

 

[JHZR2]

there is no harm, but Im not sure if its a "best practice" to do so without a reason...

I tried Maxlife full-syn and syn-blend in my 370k miles some years ago when it was more than 200k miles on odometer, Maxlife didn't do anything to the engine oil consumption of about 1/2 quarts in 3-4k miles since new. I switched back to normal dino and syn and nothing good or bad as the result.

My E430 has more than 150k on odometer and I don't think about HM for it, I just use standard syn oil.

Maxlife full-syn is very hard to find in So Cal, if I like to use HM oil then M1 HM is probably the easiest to find here.

Honestly I wouldn't use a HM oil until its necessary i.e. burning or leaking on a regular basis. My recommendation would be to keep using a name brand syn like you have been doing.

2003 Cavalier....granted, not sure I'd call it a high quality car..

Kinda my thought...

It's handled M1,PP, QSUD, Napa Syn, Synpower, and ST syn with no issues at all....

Not sure it will notice though...

 

[MinamiKotaro]

Does it leak? Does it burn? HM may help. If neither circumstance is present, no real need to go to HM, no matter how many miles are on the engine.

 

[Kuato]

Not leaking = no need for HM oil. But it won't hurt if you decide to go with the sale.

 

[Blang]

My 2003 Cavalier has been good to me. At 209k and still going I have thought about the High Mileage thing as well, but haven't tried it yet. It only seems to use oil during extended freeway driving (not tons, but enough to necessitate occasional top-offs). It's never dripped a thing (though minor seeping is present). If you keep oil in it, it should run quite a while I imagine. Sounds like you have been taking good care of it!

 

[901Memphis]

Do it, Maxlife full synthetic is hard to find for some, your engine deserves it.

Typical BITOG regurgitated, scripted, Chicken Little sky is falling responses.

 

[CharBaby]

I am almost willing to bet that, switching to dino oil such as PYB/QSGB will slow/stop the oil consumption for that 3500-4000 mile OCI!

 

[NMBurb02]

According to the HM oil labels, you're 25k miles overdue for the switch!

I will echo what most of the others have said: if it ain't broke, don't fix it. If you think consumption is excessive, then give a HM a shot, otherwise, continue with what have served you well thus far.

One of my family members went to a quick lube place and they put HM oil in an engine with only 80k km (49k mi). It is a 2007 BTW.

What is the worse that could happen from the HM formulation? Will the seals turn to jello?
