Oil debate?

[pstephens46]

Can I use Mobil One synthetic in my F150? Hard to believe it would break down as Yamaha suggests? Yamaha brand oil and filters are pretty expensive!

Last time I checked the Yamaha engine oil requirements specified by Yamaha for an F150 were met by Mobil 1 oil.

Where did you read that Yamaha says it will break down?

Literature at boat shop touting benefits of yamalube. What is the rating? FC-W?
Sounds like good news to me! Thanks!

From the Yamaha F150 owner's manual and from Mobile 1's web site

Great! Thanks

I'm sure you've noticed the number of products with the prefix "Yama," and you sound intelligent enough to know why.

as long as it is also rated FC-W it is ok.

I use Diesel synthetic oil in mine. Has better shear resistance and contains more zinc than std automobile grade oils. Marine 4 stroke oils contain more zinc than std automobile grade oils . Zinc is minimal in auto grade oils because it breaks down catalytic converters. Zinc is used as the wear protection and diesel formular most closely resembles the marine industry oils.

Who makes this Diesel synthetic? Does Rotella have a high level of zinc I wonder? Been using the 15w40 in my sons high mileage Trailblazer. Wonder if I am screwing the catalytic converters?

I doubt the diesel oil will meet any Yamaha specifications.

If the motor is out of warranty use what ever you wish.

If the motor is in warranty it might be a good idea to follow their suggestions.

You are right It mostlikely exceeds Yamaha requirements for sure.

I wonder, how many warranty claims have ever been denied due to specifically using an oil other than Yamaha brand??

What are the API specifications for the oil in question?

If other than a Yamaha brand, but if the oil meets Yamaha specification (Mobile 1 as an example), then I would presume the warranty claim denial rate to be zero. The oil meets Yamaha's specifications. They have no reason to deny a warranty claim based on the use of the non-branded oil.

Who has the time and resources to determine what brand of oil was being used in a failed motor in the first place, assuming the failure was some how oil related.

Oil system related failures are extremely low. Now fuel system related failures on the other hand are way up the list. Yamaha US pays out thousands of dollars in claims (which some will say is warranty but it is not) for fuel system related problems, trying to keep the customer happy. Even though Yamaha has nothing to do with the gasoline that anyone uses.

Let a cow eat bad grass, resulting in the cow being sick, and the cow's owner will feel sorrow and sympathy for the cow. He won't blame the farmer that sold him the cow. Let a Yamaha eat bad gasoline, resulting in the Yamaha being sick, and the Yamaha's owner will know that it is the fault of Yamaha. He will blame Yamaha and expect them to fix the motor free of charge.

I blame the EPA, Federal gov and all the sorry egg sucking criminal liberals that control it.....
