Engine oil?

[SSG 5.0]

NAPA also has the pennzoil euro 5w-40.

I think Napa got shot down in my area, but I’ll check.

To be honest it's not only about how think is the oil. It depends in the weather since the oil heat causes a chemical reaction in the engine oil, which causes the oil's viscosity to change

That’s one of the reason I started looking because of the changes in oil due to weather and having a supercharger stressing the oil a lot more.

I’m staying full synthetic although I was told before, once I made a switch to full synthetic, I can’t go back to regular oil or semi synthetic. Never read up on it and kept it like that. I wonder how true was that.

It’s not.

If you’re running any sort of performance application, I would nudge you towards any oil that meets ACEA A3/B4. As far as I know, it’s the most stringent industry spec for performance oriented gasoline engines. I prefer Pennzoil because of the GTL base oil, but mobil1 and castrol also make A3/B4 oils. You can get some 30 weights in A3/B4, but most are 40’s. It’s difficult to achieve the HTHS minimum in A3/B3 in a 30 weight, but doable.

Thanks. I read the 5W40 Platinum Euro and it’s also ok to use for diesel and high performance gas vehicle.

Motorcraft 5w50 or I've most recently switched to Castrol 5w50 - both full synthetic. 5w50 is pretty standard for people racing coyotes.

Amsoil signature 5-30 with motorcraft FL500s filter here

How about the cold starts running 5w-40 or 50s since the tolerances of the stock parts and camshafts were built by the factory with 5W20 in mind? Won't scratch everything up in there??

How about the oil pressure and oil pump on regular driving only, won't the oil pressure go through the roof and how bad that could be?

Only a procharger p1x installed, a couple of suspension parts and mainly a street car. I have been reading here in the forum lately that using 5-20 is a no go for a fi coyote? How true is that? I use Mobil1 full synthetic since the first oil changed.

Bro Mobil 1 is garbage. Even the stock motorcraft oil is way better.

I switched to amsoil, and Pennzoil platinum. Both are the best oils you can buy. Their are unbiased tests online that prove that they are the best oils you can get. My car runs noticeably quiter and smoother on amsoil vs motocraft Mobil 1 is pure trash used to run it in my old engines. Its overpriced, has few detergents, not as good cold start additives, offers mediocre protection...

5w20 and 5w40 should behave exactly the same on cold starts the difference is warm up times and once it's warm its viscosity. "5w" means "viscosity value 5 in winter temperatures"

The brand of oil has a bigger impact. 5w20 Amsoil in reality will flow and perform very differently than 5w20 Mobil 1.

Ford switched over to heavier weight oil on the gt350 because that engine is intended for track use and lots I high RPM. the regular 5w20 oil basically becomes too thin at high temps in that situation and the heavier weight oil should offer better protection for the bearings. The drawback is reduced gas mileage and longer warm up times and you have to make sure not to wail on it until it gets up to temp.

In theory going heavier than 5w20 with forced induction is a great idea but not necessary. (Meaning the car will run on 5w20 ok) the supercharger uses its own oil and you didnt change any of the clearances inside of the motor...

Going heavier just offers more protection since you'll be building revs way faster than stock.

Id suggest going with whatever whipple, recommends or what ford suggests for the supercharged aluminator and coyote engines. Ford performance actually has recommendations for supercharged applications just google it.

I suggest not taking advise from a web forum on something as critical as this. Or at least take the advise with a grain of salt

The problem is that I always go with turbos or centrifugals superchargers with a lot of boost and for those you have to tap into the oil pan to feed them and share the same oil as the engine as you probably know.
Thanks a lot for writing all that and this is a tough one as usual and each person says a different thing and some don't even believe one oil is different than the others. I even had guys telling me that the same guy that goes to fill up the Mobil Drum is the same one that fills up the Castrol Drum and so on and only the labels change... It's definitely one of those topics to make us scratch our heads sometimes.. but I understood what you said and thank you again and don't want the oil of my engine turning into water with all the boost of the turbo.

@3star2nr is correct that the cold number is the same between the oils in question. If someone suggested a 10w40 or 20w50 I would warn against cold weather cold start situations.

 

[engineermike]

FYI, the 2020 gt500 also calls for 5w50 at temps above 0 f and gives the option of 0w40 at temps below 20 f.

Yeah thats the other advantage of superchargers since they dont tie into your oil system.

But yes the manufacturers buy tge same oil but they blend them differently and add additives that are specific to each brand. The viscosity rating is basically determined by measuring the time it takes oil to travel through a standard sized orifice at controlled temperatures. The ratings is a range so if it takes an average time of 5-10secs to go through X orfice the oil gets a Y rating.

Thats My understanding at least. Some brands will flow better than others. And what youre paying for is the additives

im supercharged also, i change mine every 4k miles depending how hard i drive it in the spring summer and fall months pennzoil is all i have been using. i've ran amsoil, motul, ford semi syn.in dif cars. soon as i got this i went full syn even if i change it more often then what most do .. its a supercharged car and we all know we get on them a good bit .. just good insurance to me and pennzoil isnt to pricey
