High Mileage Oil

Just 5 days shy of a full year on this thread bump...

I'm at 101K miles now on the X-Runner and 87K miles on the Impala, Still no leaks using Royal Purple 5w30...

 

Good to hear.

 

Mobil1 since day 1. 91K miles no intention of changing
High mileage oil=snake oil

 

Just tons of hyper bole it's just oil with a different label.

 

Really, guys... I can't stress this enough. Read this:

Don't do it.

Once you use HM oil and swell the seals and gaskets, you will likely have to continue using the HM oil to prevent new oil leaks.

Unless you are having issues with seals and gaskets that the conditioners in a HM oil would possibly help with, I would not use it.

I am still using regular Mobil 1 Extended Protection 5W30 in my 2006 at 354k miles with zero problems or leaks.

 

Agreed, if it ain't broke don't fix it. I wouldn't use HM in a lawn mower. Just my2c

 

The additives are slightly different.
The Mobil-1 high-mileage does not meet the same "green" certifications for fuel economy.

Likely, added viscosity improvers to hold heavier grade for the 10k most synthetic users are sold on.

 

The Mobil 1 High Milage oil is API SL-rated rated while normal Mobil 1 is API-SN rated, a newer standard with lower levels of zinc as an anti-wear additive. The higher levels of zinc anti-wear additives can reduce the life of catalytic convertors, which is why the newer standards allow less of it.

The viscosity of HM oils do not hold up longer than typical synthetics, all of which can easily go 10k miles in most engines.

 

This was a great read, thanks.

 

Pretty smart stuff it knows the difference between paper gaskets and rubber seals and acts accordingly! There are more brands of oil on the market then cereals every one of them screaming buy me I’m the latest and greatest it’s the same thing as pure synthetic that isn’t.

 

I just switched to all synthetic in my rider anxious to see if it runs any better this year.

 

I have just hit 350.000 ...

 

Congrats. What model year is your truck?

 

What is the number one recommended oil for the Tacoma. From Toyotas perspective and users here. Thanks.

 

Mobil 1 by a mile

 

Is that what Toyota recommends or just your choice.

 

Just watch this:
Regular oil changes with normal Mobil1 coupled with good quality gas is all you ever need.

"I heard a commercial on the radio..." followed by "high mileage", then "after 75,000 miles" all in the same sentence does not sound trustworthy. That guy lost me at "75,000 miles is high mileage".

 

Mobil 1 is my choice since the first miles when the truck was brand new on day 1. Now have 387k trouble free miles, no sludge, no oil burning.

 

To prevent carbon build up.
