Here is a summary report of my Mobil 1 with about 5000 miles oil life indicator was at 41% Previous changes at 1000 and almost 5000 miles were not sampled. Car now has 9811 miles.

JAMES: We're not seeing anything out of line in this first sample from your 2014 Corvette's engine. Wear
metals look exceptional compared to universal averages, which are based on about 3,400 miles on the oil
for this engine type. Considering this engine is still pretty low-mileage, we might have expected some
lingering wear-in stuff to show its head, but really that wasn't the case (and that's fine). It just means your
engine is maturing well. We don't see any apparent issues here. No contamination like fuel, water, or
coolant was found. Looks great at 9,811 miles

 

Mind posting a pic of the analysis sheet? Blackstone? Glad to hear your engine is wearing in properly!

 

James,
Thanks for the information. It sounds like the few oil changes right at the
beginning worked wonders to get all that extra wear-in stuff out of the
engine. Also, since you noted it was a 6.2L engine, I've updated the report
just a little. We had the 5.7L engine recorded. I'll send an amended report
this afternoon, though the only thing it changes is the universal average
column (different engine, different averages). Your engine still looks
great by comparison, so the comments don't change much.

We'll look forward to that next sample!

 

Looks great!

 

I sent my new honda accord to blackstone in 2013 with 3500 miles on it using mobil 1...the answer came back, "you are good on this oil load for another 10,000 miles"

 

Excellent

 

Running Mobil 1, I'd feel comfortable taking the oil life indicator all the way down to 0% knowing that it will still have life (and additive pack) to spare.

 

There's a group of you guys that take "worry" to a new level.....

I've got 600K miles in Corvettes, 300K miles in P-cars and LOTS and LOTS of miles in other cars over the past nearly 60 years of driving and simply changed my oil on a regular basis...

I have had one - one - engine failure - a Porsche in '65 - the dealer took the car in, replaced the engine, and life went on - I have zero idea what the failure was but I'm betting it wasn't oil because we all changed oil at 3,000 mile intervals back then.

No one on his death bed has ever said, "I wish I had had the oil in the Vette analyzed" - unless he was terminally stupid or suffering from dementia....

73 and NOT suffering from dementia... nor fear of engine failure.... three months and 9,000 miles on the C7...

 

Thanks for the post.

 

This report speaks to effectiveness of that early 1000 mi oil change. Obviously they are used to seeing lots of grit in new engines!

On a leased Corolla 14 model I have, the dealer sent me on my way without oil change at 5k maybe I should have a sample of that oil?

 

I've been burned too many times to take the " ignorance is bliss attitude". Been contemplating messing with AFM/DOD perimeters and possibly shucking the power train warranty to have a car drive like I want it to> Thus oil analysis was in preparation for possible mods to the programming.

 

I wouldn't spend an unneeded cent on maintaining a leased Toyota unless you plan to buy it out in the end.

 

It's not an "ignorance is bliss" position.... it's several million miles in cars - including 600,000 in Corvettes and 300K miles in P-cars. It's just shy of 60 years of experience and the input of dozens of technicians with Porsche, BMW, GM, Audi, MB and other makes throughout the US and four other continents.

Your car, your time, your money...

Its more interesting to me to know the how and why of even my washing machine. I could not have and engine failure with no knowledge of why and go on like it never happened. I am glad there are people that always look for ways to improve these machines and interesting to find out why anything is engineered the way it is!

 

Iron is a bit high for 5k, although that should probably come down as the engine breaks in a bit more. What really surprises me is the viscosity, it's now a 5w20, and Mobil 1 5w30 starts out around 11cst at 100c, so it dropped a lot more than it usually does. In my oil analysis reports it usually keeps it's viscosity right at 11cst, and rarely goes below 10cst in most reports I see. There doesn't seem to be any serious amount of fuel in the oil either, which would thin out the oil. That's something that worried me when I heard that GM was going with direct injection on the C7 as I know from other GM DI engines that they tend to how a lot of fuel dilution in the oil.

 

Thanks for comparable info, I will keep it in mind. In the mornings when I start the engine it seems to take a few seconds to hit on all eight like a cyl is loaded with fuel. So I too was interested about fuel dilution. Common in diesel engines when something is amiss! We used a vis-gage to check diesels quite often which compared two ball bearings sliding through glass tubes one with recent sample the other side fixed compare sample oil. When temp stabilized the ball bearings would travel the same unless sample oil was diluted then that side would fly down hill.

 

So just because there are people who are interested in this type of data it makes us demented? That's a pretty lame thing to say

To each his own, and if you don't want to do it yourself, there is no need to berate those of us that do. I've been doing oil analysis on my vehicles for about 15 years now, it's a fun hobby for me and it has allowed me to pinpoint a leaky fuel injector in my daily driver and get the problem rectified before it became a lot more serious. I know of a few people who have found the beginning of a head gasket leak on their engines, thanks to oil analysis, and were able to fix it before a more costly repair took place. So it does have it's mechanical benefits. But number one for me, is simply an interest in knowing what's going on with my cars. Nothing wrong with that at all, it's really not much different than someone who is curious as to what kind of gas mileage their cars get, or what it runs in the quarter mile.

I'm not trying to push oil analysis on anyone, and nowhere would I possibly say that's it's all that cost effective in a case like mine, since I do it after every oil change. But I do know a few people who were comfortably able to extend their oil changes a lot further than they were previously comfortable doing, after they say the oil analysis report showing it was safe. So in the long run they saved money because of having the oil analysis done.

 

Who cares, it's a leased car! do the recommended oil changes and you'll be fine lol. you're giving the car back. It's not even yours really! LOL

I don't take care of my lease cars like I do my owned cars. Our infiniti gets an oil change like every 7500 miles (dino oil too) and the volt is driven until oil % says 5 or less. Currently at 14K miles, it's still at like 40% lmao...

If anything honestly, it's more of a curiosity killed the cat kind of thing here. at least for me

 

Machining and technology has come a long way in 60 years, so what was right then doesn't always hold true today as more sophisticated oil and better engines don't have the same issues as 2 decades ago, so you can run synthetic more than 3k miles, if you want to waste your money on that interval oil changes, then awesome!

 

How do you go about sending that in for analysis?
