howdy,



does anyone know what's the best synthetic motor oil out of these?



- valvoline synpower

- royal purple

- redline

- amsoil


my lightning has only 900 miles on it. i've heard it is recommended not to use full synthetic until 3,000 mi. some say, 6,000 mi. is this true?



thanx for any info.

 

Any one of the synthetics you can't go wrong with. If your truck has 900 miles on it I wouldn't add synthetic until it has a few thousand miles. You need to get the rings fully seated first. That's why they advise against using synthetics to break a fresh motor in.

 

I use mobile 1 or royal purple and they both work great. I wouldnt use anything else in my Harley Truck.

 

:sorry I Hit Key Two Times

 

What advantage would these oils mobil 1 etc/ have over motorcraft 5-20 which is probley 70-30 blend i don't know for sure lets have some input please
you don't know if you don't ask????????i have JDM BUILT MOTOR

 

What did they recommend?

 

They're all good. If you do a search on here, you'll out what individual guys like to run.

 

i have a JDM built motor im running 0w20 Mobil in mine.

 

Jim at JDM said "Use This One"



All bedded in now, oil,filter & plugs changed.
Ready to Dyno on 29th Sept.

 

I have heard that you can't beat 5-20 motorcraft in a lightning some say it will pull 5-10 more horsepower on dyno with motorcraft over mobil 1: besides when i take my 2003 red lightning with JDM BUILT MOTOR to ford dealership to change oil a crowd gathers like you wouldn't belive mabey 25 or thirty to look at my lightning they can look but cannot touch only one person changes my oil whom i know

 

Yeah I was supprised how thin it was - like ****

But it's what Ford reccomend.
And my engine builder / tuner reccomemded.
It's not easy to get here in the UK so when I bring something in from JDM
I will add a case or two each time.

 

Not using synthetic motor oil to break in a motor is a myth. The only thing I wouldnt do is put it in a fresh rebuilt motor because you drain the oil so quickly(50-500miles). That would be a hit in the pocket book but other than that there is no problem. And also rings seat in about the first few minutes of starting a new engine and they will seat just fine with synthetic.

I use Amsoil, but any synthetic will work. Changing the oil regularly is the only thing that matters IMO

 

 

Jim is right on he knows what works best for our lightnings
