What is the best oil to put in the 5.4L 3v

[Gruz7]

What do you guys recommend?
Synthetic or what?

Synthetic is better.

Not all oil is the same. Honestly do some research on a oil brand you like compare to other similar brands and go from there. UOA will back up or disprove what's really going on.

Now that I have stopped my oil leak I will start oil testing to help my exp last longer.

In my opinion the cold starts on these things are rough. Every 5.4 I have driven rattles loudly until oil pressure picks up.

I agree 100% with the cold start thing you mentioned.... I'm planning to go 7 quarts of Mobil 1 full synthetic and a motorcraft filter for my oil change on Wednesday.....

Due to my lifters/phasers/chain/solenoids (don't know quite what is causing the noise just yet) my uncle is thinking I should to throw a bit of Lucas additive in there... Sounds like a scary idea to me

I have put about three cups in my oil. It helped a lot with start ups.

In the past I have stayed clear of oil additives. But the Lucas increased the viscosity enough to help the oil stick. My start ups are noticeably quieter.

I to am running mobile1. Even though it is not a true synthetic. Or in my opinion is not a true synthetic.

I added Lucas because I did not want to increase the oil weight at start up. But I will not know until I get back oil tests.

I am running the 10w -30 now.

Good luck. Let my know what you find in your research.

Thanks for the advice and I will! Gotta figure out what my issue is crazy shaking and knocking I hope it isn't time for a motor swap

Let clarify the extended life is a true synthetic. Regular mobile 1 is still group 3.

Good luck.

It seems like a lot of people prefer motor craft oil. I have always used Mobil 1 on my other cars. 5qt jugs of extended performance at Walmart are cheap. I like the Lucas stuff too.

I use the MotorCraft Synthetic Blend, also have a bit of a "rattle" at startup, especially in the cold months, have thought about Lucas, reading that some have had success with reducing the noise I'm tempted to try it.

Guys if you use syn oil make sure you use a syn filter. Putting mobile 1 oil with motorcraft filter bypasses the point of having synthetic oil in the first place.

Fram extra guard
Mobil 1
K&N
Royal purple
Those are examples of synthetic oil filters

Man I must sound like a newbie... I had no idea they made syth oil filters, I guess I can get a Mobil 1 synth filter at autozone/advance ?

Purolator premium and motor craft are the same filter. Both good filters.

But I still gotta get a synthetic filter if I run full synthetic oil though right ?

Yes the mobile1 synthetic filter in my opinion is very good. Excellent filter and anti drain back is good too.

Ok I'll give that a go and see it gets rid of the violent VCT shaking and noise I'm getting

Good luck. Plus remember these are my opinions. A good oil and filter combo is the blood flow to a healthy engine.

Hey Gruz. I'm not sure the oil change will solve your problem. I hope it does. I used to use slick 50 before I ran synthetic. I'm pretty sure zmax is snake oil. Sometimes I still put marvel mystery oil in the crankcase right before I change since it's cheap.

So I use Mobil 1 because about 30 years ago my dad had a Mobil station. I'm sure it was a sales pitch but they showed him the difference between conventional and Mobil 1. Even back then they said Mobil 1 could go
10000 between changes.

I use the extended performance with a Mobil 1 filter now in most of the fleet. I'm not trying to be a fan boy or sell you on this stuff but it's cheap and easy. Usually autozone sells the extended performance and the m1 Mobil filter for about $34-38. Cant beat that if you do it yourself. And I always go 10000 miles between changes l topping off if needed.

Thanks that's what I think I'm gonna do and I think it also won't solve my problem I just want to clean my gunked up VCT solenoids the best I can so replacing them in a week or a so isn't so hard and this will be a trend for me now as I don't believe I can trust anyone to do my oil changed anymore.
