Richard- I never stated that Rotella darkened after 10 hours. I said minutes. I also said Regular JD oil, not Rotella. I had a JD dealer install JD oil when I had a starting problem and after they started it up the crap, yes crap oil was black. For the money JD wants for their oil is BS. Better oils out there at 1/3 of the price (synthetic too). The big thing with diesels is acid, soot, and TBN.
Side bar: As far as the Ford diesel page is concerned half the people on there are scared to death to stray from the “little Ford book”; they take there truck in too the dealer for repairs just to follow the book or keep receipts to get a huge $500 dollars of their next truck! The problem with the oils was foaming a few years ago. When they have a problem do you think just because the dealer worked on it, the truck problem is Ford’s problem? Come on.
If the oil was tested at 5K way change oil? I guess some people like to throw money away (general statement) and valuable time! In my manual it states that the interval is 5,000 miles regular and 3,000 miles for severe and that you SHOULD use oils that conform to SAE specifications, that’s it. It never stated that you must follow Ford recommendations. As these are just recommendations not “set in stone”. The warranty is for a short time period compared to the track life and so if your dealer allows you to go 5,001 miles you would void warranty? It however amazes me that people listen to Ford when they will do everything in their power to prove the customer wrong EVEN if they followed the “little manual”.
Bank is a completely different animal, which is not on the topic basis. The manufactures like Banks and Amsoil should help the customer. If these few, and very few people, had problems they probably did not adhere to the manufactures guidelines for their intended product use!!
I run Amsoil (drain every two years) in my Suzuki GSX-R1100 with turbo and it produces near 200 hp and I had a major engine problem. I test oil every fall to see if turbo is running correctly (and it does). So, Suzuki thought they were going to void warranty because I don’t follow their oil recommendations and because of the turbo. Well, they Suzuki lost and it cost me $1,500 for my brother-in-laws party for winning (lawyer ,now Judge) and cost Suzuki over $4,000 for new engine. So if you pursue things with the proper people you will win. There are many loopholes in laws. You just have to look.
So by what you have read which is a general statement. Why do military aircraft use synthetic? I work in the Aerospace field and they do! What happens if you can not use a heater in the area they are in, then what? The research article is wrong, period. If you read some ASTM or SAE standards will prove this research article is wrong. I don’t believe it either.
As far as the five minutes is concerned. A lot could happen in that time. If my baby boy talks for the first time I want to be there and not messing with some oil for a tractor! The time I saved to spend with him is worth its’ money in gold. I don’t have warranty concerns either. My Ford dealer knows what I am doing and they approve of it and my tractor is/was out of warranty any ways. The newer tractor will also run a synthetic oil. Only the best oil for my equipment..
Have fun guys and remember this my understanding and learning. Not said by God. Everyone can do whatever makes you smile.
Thanks
