What is in Motorcraft oil that makes it "semi" synthetic? Why not all synthetic if its so good? Whats the benefit of having half of each?

 

half dino oil half synthetic i would guess.

 

It isn't as good as full synthetic but it is half the price per quart and ford beleives itis adequate for their vehicles.

 

 

At least with a Ford, you don't have to use a full synthetic oil or 91 octane gas. You can still run with semi-synth & 87 octane.

 

Most "Blend Oils" are just that a Blend, it's not a 50% ratio of dino to synthetic like most people tend to think! Usually the ratio is 25-30% synthetic to dino! That is why I use a full synthetic..........

 

You'll find that the Motorcraft semi is a blend oil. In the case of Motorcraft oil, unless something has changed recently, it was being bottled by Conoco-Phillips. It had the same formulation as the Phillips Trop Artic and Kendall oils. Both of these use far more GP III synthetic basestock than most other blends with the percentage closer to 60% per tech at CP. FWIW, the blends are the best of all of the oil technologies and turn in the lowest wear metals versus full synthetics. There is no standard as to how much synthetic has to be in the mix to be a blend. Apparently, a splash will do.

 

I thought you used Mobil 1?

 

LMAO!!!

 

Mobil-1 is not a blend!.......

 

It's also not a true synthetic in the Amsoil/RP sense - it's dino-based.

 

Which Mobil 1 are you using? Some are full, some are not.

 

I use the regular Mobil-1 5w-20, with a Motorcraft FL-820's filter at 3K intervals religiously! Yeah it may be overkill, but my friend has done the same
with his old Ford Ranger/ same regular Mobil-1 3K change intervals & is currently at 400K miles, & engine runs fine!............Really can't argue with those results!............

 

If you change at 3K almost any oil will do the job. Save yourself some money. The Motorcraft oil lasts longer than 5K.

 

I want to beat the Guy's record on www.millionmilevan.com , so I'll maintain those maitenance practices!........
