Synthetic vs. Dino
From the for what it's worth department.
After speaking with one of the members of this forum about the value of synthetic versus dino oil (thanks Bob) for my 1993 8V92 I made the switch from straight Rotella 40W to Amsoil 15W40. The results have been nothing short of amazing as oil consumption went from around 1 quart per 250 miles to about 1 quart per 850 miles when I am pushing it hard, to pretty much nothing when driving 55 or 60 MPH. The 40W used to get that diesel black color within a couple hundred miles of an oil change whereas the synthetic oil is still quite clear even after 3200 miles. The engine used to smoke some when leaving a stop light but now has to be fully floored to put out much smoke at all. The coolant is also not running quite as warm thus the fan is seldom kicking in any more. More than likely fuel consumption has also decreased but since I do not keep track I can't vouch for that. It is quite obvious to me that something good has taken place with my change from dino oil to synthetic. Next step is to change the other lubricants as well. I am not trying to start a war here but am just relaying my experience "for what it's worth".

Synthetic vs. Dino
Thanks for your insight. How many miles traveled are you basing your report?
In other words, how many miles accumulated since the oil change?

Synthetic vs. Dino
MY 6V92 has 15-40 amsoil in it and am suprised about the low consumption, have
not added any. I bought it with this oil being used and after reading I think the oil recomended is special straight weight for DD engines. That being said and after much research I ordered some amsoil,[which have never used before] i checked and it is very low in sulfer etc. So will use the marine-diesel amsoil this change and read more, am still not sure if is the right way to go, but these things do not cool the best so maybe?Previous owner was also using syn. tranny fluid so guess will go that route also and diff. syn. 90- 140.which i think has dinno in it now. Wish I new the real answer to this?Marvin SkaggsBuffalo, Ky. 427161984 PT40--- On Mon 04/10, whynotam < aamiller@... > wrote:From: whynotam [mailto: aamiller@...]To: WanderlodgeForum@...: Mon, 10 Apr 2006 14:47:06 -0000Subject: [WanderlodgeForum] Synthetic vs. DinoFrom the for what it's worth department.After speaking with one of the members of this forum about the value of synthetic versus dino oil (thanks Bob) for my 1993 8V92 I made the switch from straight Rotella 40W to Amsoil 15W40.

I put eighty thousand miles on a 6v-92 using amsoil 15/40 and have 50
thousand on my 8v-92 using amsoil. I also use the amsoil syn transmission fluid along with the rear dif, fluid. My Dodge diesel pickup truck has 100 thousand with amsoil in it from the first day. No complaint's. I have the oil analysis once a year on all vehicles and no problem's. I would never go back to Dino..

Hi Bob,
Your 80k miles on the 6v-92..is that without an oil change? Just put in dino in the engine with synthetic in tranny (Amsoil). I wonder if I decide to switch to Amsoil in engine how many miles I have to have on it before draining the dino oil. At present, I only have 5k miles on the rebuilt engine.

If your engine rebuilder gave you special break-in oil change
requirements (shorter interval), use the cheap oil to the first change. if not, you can change at any time, breaking in an engine with syn oil in it is fine and recommended by Mobil. Dino is fine, synthetic is better. Holland Motor Express used to run Mobil Delvac 1 in their 6V92 fleet, changed it at 250,000 miles during a major maintenance, filters in-between. I don't know if it has changed, but last I knew the Delvac 1 has no viscosity modifiers. Synthetic trans fluid I highly recommend as it has a higher thermal transmissivity and will run cooler, one reason it is popular with the towable-RV crowd, it made a noticeable improvement in trans temps during retarder use in my '88. ZF allows triple the maintenance interval with synthetic trans fluid over conventional/dino fluid. Lots of money, and as many will argue the coach will run fine without it. - Jeff Miller in Holland, MI --- In WanderlodgeForum@yahoogroups.com, "Bob Lawrence" > > Hi Bob, > Your 80k miles on the 6v-92..is that without an oil change? > Just put in dino in the engine with synthetic in tranny (Amsoil). > I wonder if I decide to switch to Amsoil in engine how many miles I > have to have on it before draining the dino oil.

Bob,
I have been using Amsoil in every internal combustion engine I own since 1979. At 5,000 miles, with modern ring technolgy everything is broken in by now and you are OK to switch, but since you just had the oil changed, switch at 8-10,000 and get your money's worth out of the last oil change. When you switch, make sure you get a good quality synthetic oil filter also: Amsoil, Mobil-1 or the new Donaldson line. The synthetics don't break down, but they will load up with dirt and soot just like dino oil. You need excellent quality filters to preserve your synthetic oil investment. The paper based filters are are a waste of money and synthetic.

Mike,
How are the synthetic filters different from conventional filters? Do you have part #'s for the proper filter to be used while using synthetic engine oil?

Jay,
Regular oil filters tend to cellulose based, commonly referred to as paper. If you ever cut a regular Fram or AC filter open it is typically just pleated paper to increase the total surface area of the paper filter medium. Cellulose is basically broken down soaked wood chips made into a paste and then compressed into sheets and dried to become paper. As a result, cellulose fibers are inconsistent in size, shape and thickness. You have thick spots and shallow spots in the paper. Thick spots result in higher restriction and lower dirt holding capacity. Shallow spots allow more contaminants to pass through and can even rupture into mini-holes allowing unfiltered oil and contaminants through. It is the very small contaminants that cause most of the wear in engines over time. As time goes on, the hot oil will also degrade the resins that bind the cellulose media together, which allows even more unfiltered contaminants to pass through. If you get lucky and get a particular thick piece of cellulose, it can get saturated or totally plugged up with contaminants and then start bypassing unfiltered oil through the filter bypass valves. That's what they are there for, to prevent engine oil starvation in the event of filter restrictions. The synthetic grade filters typically use a manmade synthetic media which has very controlled fiber density of uniform sizes, shapes and smaller diameters. They are then typically layered in various densities with wire screen backing for shape and strength. they are compressed at a consistent rate to eliminate thick or weak spots. They then have consistent flow rates and more fully filter multi-micron size contaminants. Precisely measured tests prove them to be far more efficient at cleaning pre-measured contaminants out of oil passing through them. With synthetic oil, use good synthetic filters and change them half way through your life cycle of usage. For even more efficient cleaning, several manufacturers sell bypass filter systems that use even denser synthetic media that can clean down into the one micron range. These bypass filter systems typically use a restricted oil orifice, typically off the oil pressure gauge sending unit, to pass small amounts of oil at a time through the bypass filtration system. Due to the dense filtering restriction, it typically takes 7-15 miles at highway speeds to pass all of the oil through the bypass filtering system, which cleans the oil back to nearly new state in terms of contaminants. An early version of these deep cleaning bypass filters were commonly found on the mid-80s PT Birds. Many of them have been removed since they were so dirty to change. I know mine was missing on Stagecoach - only the documentation in the Blue Box remained. The new bypass filter systems utilize spin on filters and are much easier to service. Supposedly, you never need to change the synthetic oil again with synthetic filters and a synthetic quality bypass filter system. You just change the filters regularly and top off the synthetic oil supply. I have a bypass system I haven't installed yet. Amsoil has an interesting tear down test on a class 8 diesel with 400,000+ miles that had a bypass system and only changed filters during that time. Ironically, as regards air filters, the most effective air filter tests that I have seen are not cellulose/paper or oil treated synthetic filters, but the old oil bath filters found on the Perkins gen sets. So if you have one of those, keep it. Per your question, the synthetic oil filter cross reference numbers I have for the 6V and 8V are as follows: Amsoil SDF72 Donaldson Endurance ELF7670 Hastings LF262 Fleetguard LF670 LuberFiner P670/LFP911 I have the Perkins oil filter numbers in the old bus log, which I don't have here right now. I believe the Amsoil oil filter # is SDF96. Actually, I think I posted a cross reference list in the forum files if you need them.
