I heard a lot of good thinhs aboiut rotella. Does it really clean the crap out of your engine? Like to the extent that when you first switch to it you should change your filter every thousand miles for 5000 miles? And how long between oil changes?

 

I read that the reason people get leaks after switching to synthetics, is because they have higher detergent in them and they clean the sludge out, which may have been stopping up the leak. Im not a scientist, just what I read. I use synthetic in everything except my cummins bc I cant afford 3 gallons of it every oil change. lol. I talked to a parts guy, he said next gen was really good because it had a lot better additives package. Again im not a scientist just reporting what I heard.

 

The synthetics have smaller molecules, which helps in lubrication.

Some people think that lets them squeeze out between gaskets better, but that is not true.

I switched to Mobil 1 in my '87 Cherokee at about 180,000 miles. At the current 207,000 miles there are no leaks. Original engine.

Synthetics' polymer chains resist shearing better than dino oils. That is why they last longer.

8,000 miles between changes on synthetics, maybe up to 11,000 miles depending on the engine, is about right.

How's that for conserving natural resources?

 

So does this "recycled" oil... Honestly, it's just a fad they're trying to make a profit on.
How about instead of writing a bunch of opinions instead of facts when it comes to this oil, you take a trip over to BITOG and READ about it?

 

I'm pretty sure in one of the above posts I made reference to BITOG. I just can't remember the title of the thread.

Edit: I guess I'm out-dated. Can't find the original thread I had read, but all the new ones from BITOG seem to approve of this NextGen stuff. It's 50% recycled oil. I couldn't find any UOA charts, but someone said they were good. Use it or don't use it is the owners choice. 2 reasons I won't be using it: 1) I still don't think recycled oil is as good as fresh oil [this is my opinion], 2) NextGen doesn't have a 5w40 as far as I know, which is what I use in my XJ.

The '07 Focus will still get either Mobil 1 or continued Valvoline MaxLife.

Also, in regards to 'READ' about it, I don't spew pointless and baseless opinions and ideas. If I have an opinion, it has a bases on something factual that I have seen. And it's not like mine or anyone else's opinion is pure fact... that's why it's called an opinion, and is labeled as such.

 

Currently running it in my 04 grand prix. Oreilly was out of conventional 5-30. It has been fine for ~3000 miles.

 

Okay so basically im getting this out the thread: nextgen is supposedly good oil but nobody wants to use it because theyre skeptical of recycled oils. And Synthetic oil can be used in the 4.0. What grade for a south florida summer? 10w-40? And does rotella oil really clean the hell out of your engine that you need to change the filter every thousand miles a couple times?

 

No. I am using Rotella, and I'm at a thousand miles maybe and my oil is still golden. I mean, if the engine was seriously neglected forever and has sludge, then yeah, change it every thousand miles lol. But you seem like you stay on top of maintenance, so I highly doubt it applies to you.

Yes, synthetics are fine in the 4.0.

As far as Nextgen, I'm trying to avoid anymore arguements, so just go to BITOG and decide for yourself if you want to run with it.

In south Florida, where it's hot all the time (I'm fat, so anything over 70 is hot lol), 10w40 or 10w30 would be fine. Your call.

 

Okay well i got all the info i wanted and then some. Thanks to all. If anybody wants to argue or point something out by all means please do. I dont think the topic of oil ever gets boring lol

 

This concept of recycled oil has been done before with poor results. Valvoline Nexgen is 50% recycled oil that is filtered, then blended with new base oils and added chemicals to meet SAE and API specs.

Used motor oil contains high levels of carbon, hydrcarbons, ash, metalic particles, and scale from being circulated, heat cycled, and from the combustion process.

The reason why ASE Master techs don't like it is because even though the used oil is filtered for these impurities, it's molecules have already been broken down from previous use are not as stable as new oil made from pure base stock. Plus Nexgen did not pass the ANSI bearing load test as they hoped. At 50% recycled oil, it will not last as long as new oil from base stock.

So if you want to compare carbon footprints on Nexgen vs New oil. It actually take more energy and resources to produce a quart of Nexgen then new oil. Which is why you pay more for it. The process to filter, blend, and purify is expensive for now. Once Valvoline makes the process for cost effective, the price will come down.

The source for used/recycled motor oil is used in three industries. The recucled motor oil industry, heating oil industry for furnaces, and bio-desiel. Bio-Desiel is also a blend, pure bio does not combust well and does not flow well in colder environments because it gells.

Since the heating oil industry pays more for recycled oil and has been recycling oil for decades longer then the other two industries, companies that want to recycle oil for re-use in vehicles are competing for the same resources. Good ole supply and demand.

I'm not saying Nexgen is bad stuff, only that they have a ways to go to make it competative with new oil. And knowing Valvoline, they will get it right.

 

Conventional oil begins to break down as soon as 500 miles, and 1500 miles for synthetic.

Still 3000 miles change it, or else

 

i have been running it for about 1000 miles, no problems so far everything sounds real good. just my 2 cents!

 

No, that's wrong.

 

Earlier you said 2000, now you say 1000.

It doesn't matter what evidence anyone shows you, you have your mind made up.

POW!!!! Clank, clank, clank.

Your engine, your money.

Thanks for helping the economy.

 

no point in running recycled oil if its more expensive than new oil, IMO

and about rotella, people dont use it because it "cleans out your engine", they use it because it has zinc in it, which most oil for gas engines dont have.
