In all my cars i alway do oil changes every 3000 miles regardless. More comea down to motor hours not miles. I live in a congested area and spend more time driving light to light. Also was told penny wise pound foolish, had a 01 burb with over 300k hard miles and truck is still going strong after i sold it.

The reason I mentioned it was that in 5.7 L iForce motors, the non-E85 engines stay under warranty using full synth. changed every 10k.  But with a flex fuel, they want changes done at 5k to stay under warranty.  Regardless if you say you use E85 or not.  So to them, just the possibility of E85 cuts their oil interval in 1/2???  There has got to be something to that.  Cleaner cylinders but dirtier oil???  Cooler engine but more oil contaminants?  

 

I know there are different intervals people follow.  I used to change oil every 3k when I used conventional oil.  And I think that is still a good system.  Whatever works for you.  I have switched to premium full synthetics-group 4 PAO or group 5 ester base oils.  Examples would be Amsoil, Redline, Mobil 1 Extended Interval, German Castrol (Now made in Belgium).  In modern engines, those run for 10k easily.  I've read many Used Oil Analysis on the top tier synthetics and at Blackstone Lab, they run UOA from end users and report that they still have plenty of life at 10k miles.  If you use those oils and change using the old school standard of 3-5k, you are just flushing money down the toilet.  But again, Dino juice gets the job done well if changed at 3k, just like my shop teacher taught me.  But I digress...

Well, the research I posted in the video shows engines using blends of 10% ethanol on up thru 100% ethanol exhibit no more wear than engines using gasoline.  And sampling on the used oil shows no more wear metals or degradation of the oil compared to pure gas fed engines.   Those OEM recommendations and even oil blender recommendations regarding oil changes when using E85 compared to gasoline seem to be based on similar internet paranoia that many others suffer from.   I have yet to see a oil sample from any motor using E85 exclusively that there is any significant difference, even when oil changes are the same interval as non ethanol engine of the same make and model. 

 

I use anything from full syn, syn blend, and even conventional oils.  My wife's 2006 Cadillac CTS 3.6 has been on Pennzoil 10w30 conventional for almost the entire time we have owned the car.  6000-7000 mile oil changes.  GM recommends Mobil 1 5w30.  Well, we still have that 13 year old car and plan on keeping it for a lot longer.  Not a single motor repair. 

 

Use a full syn 10w30 n my 2015 2500 6.0.  Not sure I really need to use full syn, but I do.  Once a year oil changes, very rare to go over 5000-6000 miles in a year.  I use a syn blend 10w30 in my 2013 Freightliner semi truck.  918,000 miles on the motor, no engine repairs, and it burns no more oil than it did brand new.   Average oil change interval about 22,500 miles / 450 hours. (OEM recommended oil change interval is 15,000 miles / 300 hrs).   I don't disparage anyone from using full syn oils, but very few people actually operate their vehicles in such a way that they will see any major difference between high quality conventional, syn blend, and full syn oils.

I use this app, based off my numbers its .01 difference. Computer takes 2 tank fulls to readjust and if i feel like it i could blend the fuels by alternating fuel type each week. For some reason e85 is hoveri g around 1.75, at its lowest point it was 1.37. If gas gets to 2.30 then i will switch. Maybe back in my mind i like to see the $35 to $40 fill up weekly as opposed to the $50 to $60 i did see on 87cb5999afac12b59b72192133395c501c.jpg

So at 10k miles per year you save $100-  do you change your oil more often. If I ran E85, I would follow dealer recommend and change at 5k instead of 10 and that would eat up most of $100- for Redline. Again., not bickering. Just thinking out loud. I appreciate you’re guys’ feedback

I don’t disagree with a single point you make here. Top tier synthetics are usually overkill.  But I honestly don’t think Toyota is requiring twice as many oil change intervals based on consumer hysteria. There has to be some science behind it. I don’t know what it is. Maybe on BITOG someone has explained it.  

 

Also, in the video you posted (which was cool) he was primarily focusing on wear in the combustion chamber.  How much of the crankcase was he addressing?  Maybe more E85 gets into the oil?

To me i always change oil in all my cars 3k miles always did. Would rather change oil more and have engine last. Last car i had 01 burb with iver 300k miles and its still going. Oil is cheaper than new engine i was told years ago.

I was taught the same thing years ago. And it’s still true. Engines and oils were different back then. But every 3k still works. Just not necessary if your buying group 4 or better synthetics on modern engines. Same principle though. Good clean oil is the smart choice, no matter how you go about it.

Do enough oil changes with a good synthetic on 3k intervals... you bought a new engine in like 200000 miles anyway lol.

Good point. I think 3k on conventional is fine. The main reason I use full synth is for cold start protection in cold weather. Once clean conventional is up to temp, it’s lubrications just fine. Also, the manufacture calls for synthetic on my 2 rigs. So if I’m gonna spend the cash on synthetics, I’m gonna get every last mile I can out of it.

This is the same Toyota that had  a problem with engine sludging some years ago?   Me thinks that Ye Old Toyota is also in the paranoia camp.  happens when folks get burned for screwing up.

 

Go back and watch the video a little more closely.  He specifically mentioned oil analysis.  Oil Analysis would show if the oil was being degraded with fuel.   And from hundreds of oil samples I have done myself on my commercial vehicles, if there is fuel dilution, there is accelerated wear.  And he mentioned in the video that neither was occurring.    He also linked to the study that was done, so one can get more detail.  He just highlighted aspects of the study.

 

Listen to what he is saying, not just the pictures.

According to CNBC the average length of ownership is 7 years and the average age of the vehicle population is 11.6 years.

 

Average length of time I own a vehicle? 15 to 20 years. 200,000 to 270,000 and then something non-driveline forces a burial. Rust 1 and the occasional drunk or parking lot bashing.  

 

Joe Average puts on about 13,500 miles a year. (non commercial) according to Autogravity. 94,500 miles then kicks it to the curb. 

 

At my cost IF I changed oil every 3K that is $6,000 in oil maintenance. But I change (Red Line) every 5K so $3,600. Pretty cheap motor for me all said and done. If I used a less expensive oil still of great quality (QS) I can run that down to $2,000. That isn't something that is taken into consideration in comments like the above. Is $1,600 (the difference between Really Good and GREAT) over 15 years really worth such a heated argument? Under $10 a month? Really? 

 

These are the same people that are telling me constantly that no one driving a pickup should care about fuel economy? Peppers fuel cost vs Joe Average full cost is a few HUNDRED a month. I'll spend my $10 a month on a really good oil and filter.

Agreed. And I also use Redline.

The author of this was calling the recommendation B.S. but he shared a hypotheses that made some sense in theory.  So here's the best explanation I've found so far for why E85 could call for more frequent oil changes: 

 

"E85, when compared to “normal” gasoline (which is about 10% ethanol), is fairly acidic. This acid has the ability to neutralize some of the lubricating ability of normal engine oil, but only mildly so. In fact, I would guess that regular old motor oil would breakdown more from heating and cooling over the course of 5,000 miles than it ever would from the acid inherent in E85. Normal E85 isn’t much of a threat to engine oil – the issue occurs when normal E85 becomes contaminated with water.

The combustion process of water-contaminated E85 will lead to the formation of a strong acid (formic acid, to be exact). This acid, left unchecked, has the ability to cripple an engine because it can 1) dramatically reduce the lubricating ability of normal motor oil and 2) eat away at the high-tolerance metal engine components. E85 with water contamination, in a normal engine, is dangerous stuff. Changing the oil frequently is a good insurance policy for a normal engine running E85, and this is probably the basis of this recommendation."

Either way.  Filled with E85 yesterday for $1.04 a gallon.  Now I know the station is messing up.  They are literally keeping E85 at 80 cents a gallon cheaper than regular.  Regular dropped to $1.84, so E85 dropped to $1.04.  No way they can sell the stuff and break even, let alone make a profit.  When the head shed of Murphy's figures out what this station is doing, the prices will not have the spread they do.  But for now, I take advantage of it.
