| Rumors of my death are greatly exaggerated  |
Thanks for the suggestion. I just priced fuel filters for the Power Stroke. They have the best price for OEM I could find. 30 bucks cheaper than anywhere else I could find them. "Someday I hope to be half the man my bird-dog thinks I am." looking forward to 4 years of TRUMP! | |||

Awesome, I had the same experience with my Duramax needs. A buddy purchased a cabin filter for his truck locally and later found the same filter was $20 cheaper on Rockauto. NRA Life Patron | |||

9 times out of 10, rockauto has the best shipped prices. My most recent purchase was 4 KYB Monomax shocks for my F350 last week. The least expensive shipping option said I’d get them by Friday. The 2-day option said Thursday, so I chose the cheap option. They arrived on Thursday anyway. Amazon worries my a bit because of counterfeit parts, so rockauto and Walmart are my gotos. The KYBs are replaced the Rancho RS9000XLs that where also purchased from rockauto 5 years and 100,000 miles ago. Rancho’s lifetime warranty requires contacting the seller, so I’ll see how that goes next week. I keep a set of fuel, air, oil, and even a transmission filter on hand. I usually have enough oil for the next change, which I buy when I drop the used oil off. Because of this thread, I now have oil and filters for my next 4 changes. I’m probably going to buy a set of brake pads to have on hand as well. I’m changing the transmission filter and fluid today.This message has been edited. Last edited by: trapper189, | |||

Yes, quite the list., thx. I've been watching a few more videos on motor oils in general. Different kinds of flow testing etc. it's amazing the many different kinds of additives in use now. Technology in this arena has really advanced. "Someday I hope to be half the man my bird-dog thinks I am." looking forward to 4 years of TRUMP! | |||

Question for 4MUL8R: What happens if you mix identical brands and grades of oil, but different weights? For example, if you mix 50/50 Rotella T6 5w40 with Rotella T6 15w40, do you end up with an oil that is essentially T6 10w40, or are the base oils completely different? Does identical brand oil of different weight have different additives which will affect the other weight in an adverse way, such as cold weather thinners in the 15w40, that when they mix with 5w40, will end up thinning that too much, creating something that is unexpected? I hope that question makes sense. Demand not that events should happen as you wish; but wish them to happen as they do happen, and you will go on well. -Epictetus | |||

Normally the additive package is the same in a family of lubricants. The 15W40 and the 5W40 would likely have different base oils and pour point depressants. For the 15W, it would not be necessary to have base oils with good low temperature flow. So, the cost of those base oils is likely less, and the formulation could be cheaper. For the 5W, the base oil, the thickener, and the pour point depressant would be optimized for the lower temperature flow requirement, while maintaining the 40 viscosity at the rated temperature. Shear stability would also be checked, and the amount of thickener and pour point depressant, as well as the chemical structure, would be carefully chosen. Keep in mind that the 40 viscosity is a RANGE of viscosities. So, the 5W40 could be lower viscosity at operating temperature than the 15W40. The 40 is NOT a singular value. If you mix, from the same manufacturer, I would not be concerned, particularly if the additive was the “same” as identified by the brand Rotella. ------- Trying to simplify my life... | |||

This might explain my noticeable decrease in fuel economy. I switched from a 5w40 synthetic to 15w40 conventional. I’m down from 9-10mpg to 7-9mpg. | |||

Thanks. I mixed them on my last oil change because I couldn’t get enough of the same weight, and this thread got me worried. Demand not that events should happen as you wish; but wish them to happen as they do happen, and you will go on well. -Epictetus | |||

I have a newer Discovery with the turbo-diesel that I have taken to the dealership the past two years for service. Oil changes are nearly $400 before whatever specials/discounts I can find. Looking into doing it myself, I found out that the engine has a factory oil extraction port, and that the dealer doesn't even get underneath to drain from the pan. The oil required is Castrol Edge Professional C1, 6 qts @ $16 ea. and a $7 Mann oil filter. Add $100 for a Mity-Vac for a no mess, no fuss oil change and I'm still out the door for half what the dealer would charge. I can't believe I've been paying dealer labor rates for them to pump oil out from an extraction port. I'm ashamed of myself. | |||

Times like this make me glad that my little Civic only takes 4 quarts of 0W-20. I do get the NAPA Gold filter, though. Since I drive about 5,000 miles a month, I'm changing and rotating tires once a month or so. _____________ | |||

I'm thinking about going trucking again. The desk job is getting old, so I'm thinking of firing up the old 1998 Kenworth with a 2004 era C15 CAT. Changing the oil is 44qts and about $120 in filters, and it lasts about six weeks between changes. I'm not feeling too sorry for you guys who need only 6 qts. It also uses $25,000 in diesel fuel during that six weeks, so there's that. Trucking is getting expensive.

https://windyridgefarm.us/SaeOil.pdf Above is a general non-authoritative (meaning not SAE) piece on engine oil viscosity. You'll find many such articles online. ------- Trying to simplify my life... | |||

I'll add this here too. The never mention the newer Ford requirements for the 6.7 PS diesel motors. https://comparemotoroils.com/m...a-t6-vs-mobil-1-tdt/ "Someday I hope to be half the man my bird-dog thinks I am." looking forward to 4 years of TRUMP! | |||

That article was written before the Ford spec existed as evidenced by the T6 in the article being listed as CJ and not CK. The Ford spec came about after CK spec oils became the standard. Also, that article was written by a bottle reader and contains no substantive content. In other words, the author read the manufactures’ marketing materials, then wrote an article. I found this particular quote “Shell Rotella synthetic diesel oil can last up to 500,000 miles or 10 years if used properly.” interesting when the author was talking about the oil change intervals each oil offered. | |||

The 6.7L Powerstroke was not doing well with the present and common low phosphorus engine oils. Phosphorus below 800 ppm (parts per million) was determined to be the cause. Later, a specific engine test was created to validate the performance of approved engine oils, since the phosphorus level alone can be a poor indication of the specific antiwear chemistry effectiveness. ------- Trying to simplify my life... | |||
