Hello:

I am an UBER driver that recently purchased a 2014 Chevy Impala 2.5L 4cyl Eco for rideshare purposes. This car is great on gas and works well for rideshare. Now I know I cannot match wits with a v6 or anything like that because, let's face it, I have a 4cyl in a FULL size sedan body. But it moves prety darn well for having 4cyl and being a 2.5L.

Being a rideshare person I know this car is going to have well over (probably) 200k when I am done with it. So I purchased (and I am trying to get mor bang for my buck...IYKWIM)a new full synthetic Mobile 1 had out: "Annual Protection" for a year or 20K , which ever is first.

I was using Mobile 1's "75K+ High Milage before I switched. Now I paid $25.47 for 5qts at Wally World, and it was black by the time I changed it at 15% oil life remaining on the OLM.

Do I dare try and push even 10K ~15K (nevermind 20K) with this new oil? Will a standard oil filter stand up to such scrutiny? I am NOT an automotive savvy person, so I do not have the math and science behind me (nor the $$ affordability to make an educated guess) to put PROPER answers to my own questions.

However, my logic stops when I said ok to purchasing 5qts of Mobile 1 20K for $49.84 at Wally World and the bottle stating & giving it a 20K guarantee.

Any thoughts?

Now I am not that dense that I won't check my oil when my OTM suggests, mind you, but I figured a one time try would not hurt when I can always return to the 75K HM @ the $25.47 price for 5qts...


Sorry! Forgot pics!






Cheers!

Used Oil Analysis is prudent if trying to go long on extended drains BUT that said I wouldn't even try that till out of factory warranty.
Somewhere like Blackstone Labs can send you sample containers and for a $25-30 fee measure the properties of the used oil and tell you if it is holding up and staying clean enough.

Trouble is when talking cheap passenger car oils with small fill quantities it cost you more to be responsible by analyzing the oil than it does to just change it. Larger trucks that take many gallons of oil or industrial machines that take large amounts of expensive oil the $25 analysis makes sense, for a car you can change the oil for $30 on it is hard to justify.

I would not leave an oil in for 20K just because the bottle says so, they have no idea the conditions you drive in and have not tested it in every application so anlysis is the responsible thing to do to verify.

Plus with extended drains you get into consumption and having to top off or risk running low.

We do Oil Analysis on a machine I run at work but it is $60 a gallon oil and 17 gallon fill in a $25K machine that would shut down production if it filed and be 2 weeks to replace.........

A little off topic - but a response to your post.

How is using an Uber service a "rideshare"? If the customer pays for the service, no one is "sharing" anything. The customer is paying for a product, not sharing it.

I have personally ran the 15k mile Mobile 1 for 6 or 7 years roughly on my 2010 LS. the first two years were 25k miles a year driving to and from work (85 miles a day) 90%high way/country roads. i did run it a few times (3 maybe 4) at the 15k mile change cycle. then my nerves got the best of me and i realized paying a little more for oil changes is safer than ruining the motor due to my own penny pinching.

i will note that i run the fram 12 or 15k mile filters as well. with that being said i'm doing 90% city driving now for the past 4 years and i run the oil to 8k then change it. after putting 120k on the car i've found no oil burning issues.

i would never run the oil that long without a higher quality filter in it. if you read the box it comes in they give their advertising that they filter out whatever % of contaminants. further reading online could give you more info

idk what your motor calls for but 5 w 20 i thought was a little thin...i'd stick with what the manual says (unless they're now saying to use 5w20).

just my 2cents.

Don't know about that mobil 1 oil. Never let the oil in our 2012 3.6 go far enough to have the oil change dummy light come on, usually changing it at or around 30-35% remaining oil life or at about 5000 miles but have gone beyond 5000 a few times. Standard dexos approved oil is supposedly good to 7500.

Really fwiw, hard to beat letting the dealer do oil changes when they lube everything and change with genuine delco filter, use 6 quarts of ac delco dexos for around $30. Inconvenient to have to wait, but usually they have them in and out in less than 25 minutes. Just have to be aware they are likely to try to upsell on other services while they have you there.

Yes. My 2014 Chevy Impala 2.5L 4cyl requires either the recommended 5w-20 or the 0w-20. I have never used the latter, ever. But FWIW, I not trying to really penny pinch per sé, but because I am on the road so much. I was just curious as to what others think about this Mobile 1 Synthetic oil being 20k. I have a sound mechanic that are 3rd generation owners of a 70 year old auto shop that has been in business since 1947, so I trust them with my family's 3 GM vehicles...they have bren good to me.

Cheers!

But I will agree if I can get MAYBE 10k out of this oil by checking the color/smell of it I would be happy. My vehicle is factory set to be changed at 5k for the OLM. But I tend to change it with 6~10% left on the meter.

Cheers!

.02 All oil gets dirty, the amount of suspended carbon particles blackening the oil dependent primarily upon the conditiiin of the rings and amount of blowby gases and suspend carbon deposits scraped off the oil film on cylinder walls. But black doesn't necessarily mean bad and this oil likely has additional amount of shear and anti scuff agents to compensate for normal oil breakdown aging.

But, I wouldn't trust any filter for peak performance given the extra volume of oil passed with 20K of driving compared with a 6K change. And the amount of "dirt" is progressive with time so possible filter clogging and bypass without filtration is a real issue, not to mention degradation of the pleated element or that crappy fiber valve in the "E" cores of fatiguing of the metal spring in the other filters. If you try it better have a strap type filter wrench handy for removal because the filter will probably heat weld to the seat in 20K of driving.

Have you done oil analysis to make sure the direct injection system isn't fouling the oil with fuel?
This is a known concern on these vehicles and a significant contributor to why GM came up with the Dexos spec. Just because a oil meets the Dexos spec does not mean that in your actual use it stays clean long enough OLM does not measure oil condition in any way.

His whole post reeks of an advertisement if you ask me. 1st and only post cheering on his brand.

All that I know is that I will *NEVER* go 25k miles between oil changes, so I see no reason to spend $12.40 for a *quart* of oil that claims to go 25k miles before needing changed. Not to mention that it's the wrong weight of oil as well. :)

I tend to agree - sounds like a spam AD...

I agree it sounds like a spammer or worse yet an ignorant Amsoil salesman, but figured I would let him prove that by not backing up his claims with UOA.

I'm glad the Mobil 20k topic came up. I've noticed the ads, and have many questions about this. First and foremost, who will guarantee it? Will GM support 20k miles between changes? If there's any engine failure due to using tired oil, will Mobil pay for a new motor? Will the other oil makers follow suit?

There already appears to be a trend towards longer life oils - it seems the lube guys are all steering towards synthetics as their mainstream products. I think OEM requirements such as Dexos are driving them that way. But 20k miles? Wow!

And who here wants to find out the hard way that GM is not in line with Mobil's claim? :)

I assume that, besides cleaner burning engines, another benefit of electronic fuel management is longer oil life. I've seen that trend in recent years with the oil life monitor systems calling for oil change intervals which average around 6000 miles, twice the 3000 miles of yore. But 20k is a quantum leap beyond 6k.

And, besides the lube makers and the car makers, where are the filter makers on this topic? Are their filters up to the task?

When I hear the 20k claim in the ads, I cannot help wondering how Mobil can back that up. In order for them to declare that, it seems lots of other players have to be in alignment.

Lastly, if someone's engine did fail due to the oil not lasting 20k miles, how does that show up in the tear down? That is, what other engine issues - eg, coolant leaking into the crankcase, using the wrong oil filter, stuck rings - can leave similar scars as oil failure? What might prevent the blame from being placed somewhere other than oil failure, resulting in the car owner being stuck with a dead motor and no warranty?

20k miles is an extraordinarily bold claim. But my instinct is to proceed with caution - lots of caution. Oil changes are still way cheaper than new engines.

The 90s LT1s allowed up to 7500mile change interval on regular dino oil, just the dealers and lube centers kept pushing 3000miles.

Not saying 20K is reasonable without MEASURING oil condition, just saying it is not like someone flipped a switch and said 20K, Amsoil has been claiming it a long time and at one point we had an ignorant Amsoil saleman come here with UOA he claimed supported it but he ended up going away after I used his own numbers to destroy his position. The wear material numbers were good but the oil viscosity had gone out of range, oil was completely shot and he was arguing it was good.

This is a marketing ploy to get cheapskates to buy Mobil-1 in a different jug.

Change the Oil!

A reasonable Thumb Rule is:

6 Months -or- 6,000 Miles

Nothing to lose.
If you like what happens when you stomp on it!
Oil it often!

Direct injection is a death warrant for the top end of gas engines. 1925 that type of fueling system was invented and worked well to increase hp and fuel economy. But the top end gets destroyed for a lack of cleaning by quality detergents in top tier gasoline. Yes the super oils may still do their job for 20k but u r still recirculating all that spent fuel by the egr system back into the top end. I now use synthetic oils in my vehicles because I live in a cold winter climate. If I lived in a southern climate I would go back to regular dino oil with changes every 3k miles. Have had many American made vehicles go 185k before I sold them and still never had a oil consumption/burning issue. (Just wanted a change of venue) Going back to50s, 60s and 70s cars is a different story. Just go to a BMW site and read some of their horror stories of having to pull heads and have them walnut blasted at 50k.
This story is not scientific fact just life experience. So take it with a grain of salt. :)https://www.impalaforums.com/images/ImpalaForums_toucan/smilies/tango_face_wink.png
