Okay, so I finally reached 5k on the Valvoline Full Synthetic and thought I should sample it and see what Blackstonesays. How many of you purchased their pump for the dipstick and how many of you have/use the Fumoto to get your sample? Do you have any other suggestions other than those that would be cheaper than the $30 pump they sell? Looking for other suggestions on what to hope for and expect on the report, although their sample reports look like they dumb it down pretty good. How many of you run your full synthetic for over 5k, and do you swap the oil filter out midway between changes?

Thanks!

 

I run my regular dino 15-40 almost 8k miles on a regular basis. Some sort of pump would be your best bet for now since youre running synthetic and prolly shouldnt change just on 5k miles. Im sure some other folks have run into the same dilemma youre in and have definite answer for ya. Next time you change, I recommend the Fumoto be installed if you want to continue to sample. I have one and I dont sample but once a year. Just makes it less messy when you change oil.

5k on syn you should definitely in great shape as the engine is in good condition.

 

I have the Fomoto drain valve and it works great for getting the sample. I just got my first one back the other week and everything is A ok. I dont run synthetic so cant help ya there.

 

Got the Fumoto and love it, only problem is I don't think I'll be changing my oil as often running the full syn. Unless there are some other ideas out there, I think the Fumoto will suffice for the testing samples. Any info on reports or full-syn life expectancy? Mid-oil change oil filter changes?

 

I know folks on here go 10k plus on synthetic. I think most of them might be running extra filtration with those long intervals though.

 

just got my blackstone report back. they said i could try 7,000 next time i change. that is on 5-40 rotella syn. the only thing they said was high was iron. it was 40. dont know what that means but i will try 7,000 before i change oil next time. and send a sample

 

They had me at 9K on regular 15w 40 Rotella with no extra filtration. I am running Shcaeffers right now and I am at 12K and I am getting ready to sample it and send it off.

 

Yikes! And I was ready to change mine out. Definitely curious to see what the report says when I send it in. No extra filtration means you're not swapping the factory filter midway either? I do that on my wife's car every 2500 and oil every 5k. Might be too frequent on hers as well

 

Some people think I am crazy but I run schaeffers with a bypass and I never go past 7k. You just never know when the oil will break down since every quart/gallon is different and that is when you run into problems. I mean think about it how many oil changes can you pay for for it to equal the price of a new motor. just my .02

 

I also run Schaeffers and use them for OA, it is cheaper than blackstone, you buy your test kits prepaid, so you just send it in and get the report back. I am up to 8K with no extra filtration, I assume my next OA will put me at 8k or higher.

 

Here's my report running Syn Schaeffers 9000. I run 10,000 mile intervals without a bypass filter, just the regular filter. These are the results after running my second change of Schaeffers. I ran Rotella syn from 15,000 to 97,000, then to Schaeffers. Your running synthetic so you can go more miles than the 5,000. Id go 7,000 til you figure your trends. Learned all this from the great oil gurus here. Results from Schaeffers labs::: Oil sample info: Miles on unit 116,650. Miles on oil 9,650 WEAR METALS (PPM): Copper:5 Normal. Iron:18 Normal.

Notes: Viscosity has decreased to an SEA 30 weight. Oil should be changed. Resample to establish trends. Ford F-250 diesel 7.3. My viscosity went down possibly from the change over from Rotella to the Schaeffers because the difference in oil detergents from the two, so I believe but here they are.

Mike,

My Dino Delo breaks down to a 30-weight at around 18,000. Wonder why the Schaeffer's does it before that. I'm pretty easy on the engine, however, so that may contribute to it.

In my case, that's what I use to determine a change, as everything else looks super. I run a Baldwin bypass.

I just switched over to Scheaffers 5W40 from Rotella 15W40 and figured after 5K I would switch out the filter and send a sample in. If I can go 8K I would be happy. I only put about 7-8K on my truck a year anyways.

 

Hey Pop, Whitebuffalo Rich and Jamie and a few other oil experts told me the possible reasons, there's more detergents in the Schaeffers, meaning after running the Rotella all those years the Schaeffers was cleaning things up even more, not sure though, can't quote. Also, Schaeffers labs called me when they found my sample(long story) and she asked me if I idled alot at which I told her, not out of the norm, warmups and cool downs and very little in between. I will be going to the 15-40 Schaeffers synthetic blend next per Rich's recomendations as for the shearing factor I had with that change. I take it easy on mine too Pop, once and a while I'll blow it out on the highway or soup it up just for kicks but otherwise, babied. We'll see in the future if I go the extra filtration, did it on the coolant so maybe the oil soon, we'll see, I do alot of miles so it would be benificial. For the last three years, I moved and drive an estimated 110 miles to and from work, a little over 500 miles a week so my truck is running highway constantly, whick I think is good for it, no major problems to speak of except the maintance part.

 

There are several factors that cause the oil to loss viscosity. The first oil change is the most critical time for the motor. The biggest problem may accure between the two additive packages not getting along. The second, like mentioned above, is the detergency package can cause problems at first. That's why on your first run always change the oil are your previous interval before trying to extend the drain interval.

As far as bypass filtration is concerned, there are good points and there are bad points. Most every one knows the good. It filters more wear metals preventing most of the abrasive wear. Now for the bad. Most bypass filters filter to one micron. Over time, the filter media become clogged with debris. With that being said, the holes that let the oil pass through become smaller and smaller leading to additive depletion. In other words it can strip the oil of additives. The second problem revolves around the filtration level. Let say that for some reason, something internally is going wrong in the motor and you are doing UOA. The UOA will more than likely not pick up the problem because the filter is disguising the problems by filtering the high wear metals. Thirdly no filter no matter how much if filters can not stop thermal degradation of the oil.
