Sorry that this is in one section, it sort of spans a few questions.
1.) I followed the advice of some guys I motorcycle race with and put some Rotella 15w40 into my bike. Seems like great oil, just am worried about the 15W rating. Way I figure it though is that I dont run the bike below 35 deg F so the 15 weight should still be good. What do you think? Normally put 5W motorcycle oil into it but couldnt really figure out why.
2.) I have a 2007 F150 and am really liking the Rotella stuff. I can get a 20 Gallon drum from Walmart for about $50.00 and that is crazy cheap. Only problem is that the weights are quite different than what is spec'd. Would I be okay running the 5W-40 T6 in this truck?
1. What kind of vehicle you have..... 2007 5.4L F150
2. What your owner's manual says -- not just viscosity, but certifications (look for acronyms like API SM, ILSAC GF-4,etc.) and change intervals as well...... Certified For Gasoline Engines” by the American
Petroleum Institute (API). An oil with this trademark symbol conforms
to the current engine and emission system protection standards and fuel
economy requirements of the International Lubricant Standardization and
Approval Committee (ILSAC), comprised of U.S. and Japanese
automobile manufacturers.
To protect your engine’s warranty use Motorcraft SAE 5W-20 or an
equivalent SAE 5W-20 oil meeting Ford specification WSS-M2C930-A.
SAE 5W-20 oil provides optimum fuel economy and durability
performance meeting all requirements for your vehicle’s engine.
I change it every 5000km and the recommended is 5000km but required (for warranty is 10,000km)
3. Where you live..... Calgary Canada
4. How you drive (easy? hard? fast? slow?) Fairly easy, mainly highway but I do tromp on it every once and a while. In the winter I let it idle and warm up
5. What your daily drive is like (short trips? long trips? city? highway?) 20 km each way on freeway, then probably 5 or 6 on side roads stop and go
6. Whether your car has any known problems only problem is I didnt buy it new so I dont know how good or bad the original maintenance was done so I am over compensating now trying to clean it up. Does get poor gas mileage even for a truck
3.) How does jumping viscosities vary the way an engine interacts with the oil (a link is fine, lots of threads on this site) i.e. needing 5w-20 and going to 5w-40. I know the lower rating number is cold flow and understand that one quite well.
4.) What about mixing viscosities, say you have 5-40 and some 15-40.... do you get adverse affects? or does it just modify it to a 10ish-40.
