Mobil One is advertising a one year oil change if you use their synthetic oil. Anyone doing that?

 

Never have, never will. I am strictly a 3,000 mile oil change man.

I take a labelmaker and label my next oil change interval and stick it right on my console.

I also avoid synthetic oils. If bio-oil was good enough for a dinosaur 65 million years ago, it's good enough for me.

 

Up until the past few years I changed every 3000 miles too but newer cars say 5000-7000 between changes. I am no longer able to do my own oil changes and at about $45 a shot for oil changes in my area I am looking for a way to save a buck. I can get a synthetic oil change for about $60.

 

Do they put a mileage along with the one year time frame?
In years passed they would always say 3000 miles or 3 or 4 months because the oil would break down. Obviously advancements and synthetics have changed that game.
I drive about 14k a year, not terribly many, so I would never go that route but for someone like my sister who drives 5,000 it would be a great alternative.

 

Haven't seen any mileage recommendations yet but surely there must be some. I may be wrong but I wouldn't think you could drive 14K miles on one oil change. I have two cars and probably drive about 20K a year (10K on each one).

 

For some reason I I upload a picture from my phone but their web page says 20k miles. That's way too long for me.
Would definitely work for someone like my sister which drives maybe 7k.

 

I have been sending oil analysis samples for several of my vehicles to https://www.blackstone-labs.com/ for years. I recommend that if anyone on this thread is concerned about oil.... request the free sample kit and send in a sample. Easy to do especially if you do it yourself.

You can find out how much life your oil has left in it by the TBN. What is a TBN, and who uses it? In short, a TBN (total base number) measures the amount of active additive left in a sample of oil. The TBN is useful for people who want to extend their oil usage far beyond the normal range.The TBN of a used oil can aid the user in determining how much reserve additive the oil has left to neutralize acids. The lower the TBN reading, the less active additive the oil has left.

Endless amounts of info out there... Good reading. If you have questions about Blackstone, just let me know.

 

Sorry to dig up an old thread...

Mobil says 1 year or 20,000 miles...whichever comes first for the Mobil 1 annual protection.

This is not a stretch...UOA on BITOG have shown this is easily achievable for years.

I took a Subaru fb25 (2.5 boxer 4cy) 345,000 miles changing the oil every 10,000 miles on standard Mobil 1. Ran like new when I sold it.

This is not to say Mobil 1 is the only oil that will do this...many oils are just as good.

 

That would work for me. I'm going to give up my 3000 mile oil changes for once a year. I didn't mind the 3000 miles changes when I could do them myself but a once a year $60 oil change is perfect for me and my wallet!

 

My only concern would be oil loss through the engine. I can see some poor person thinking they are all set and going 15K without ever checking the oil level....... and losing an engine due to it.

 

Stupid is as stupid does - if users make a conscious decision to reduce the oil change frequency but start or continue to neglect checking the level then they normally only do that once...

My guess is most users are either diligent in frequency and checking the level, or neglect both anyway...

 

Back when I was a kid and engines were crude compared to today and oil was a lot more primitive, oil change intervals were something like every 12K or 1 year which came first. With my newer Fords I'm noticing longer intervals. I'm usually changing my oil a little bit sooner than what Ford is recommending for each vehicle. I'd have to look in the book, but I think the interval recommended for my 2017 Ford Escape with the 2L engine is 10K or 1 year, whichever comes first.

 

Same recommended interval for my 2014 2.5L... 10K or 1 year or if the Ford diagnostic system tells you it is time. I also go a tad bit early for peace of mind.

 

My 2018 Escape 10k or until the service light which ever comes first.
2015 KIA Soul 7.5K on conventional or synthetic.

 

What about the oil filter? I can not picture an oil filter lasting 20K without plugging up and by passing thus allowing dirty oil to circulate through the engine. I change mine using Mobil 1 between 4 and 5K. I was once told that the best oil filters on the market have a life expectancy of 5K.
