Best oil filter

[802SHO]

I've always been using 5w30 Mobil 1 .
If I could find amsoil I would use that but not easy to find in my area

That's interesting bc I have Mobil 1 5w20 with this K&N.  Maybe thats a good combo? 

Usually I'm always Royal Purple 5w20 and the motorcraft filter.

In the cold months if your start up temperature is at or near 32 F you should switch to a 0w20-30 full synthetic. This greatly reduces oil starvation at start up / warm up in cold weather.

There were days last winter here in Germany, i would cringe at the thought of starting my car in the morning because the temp was -15 Celsius below zero.

Conversely, Folks living in the southern states that routinely see temps above 100F such as Las Vegas for instance, may want to run a 10w40 or even a w50 if tracking the car. I know for a lot of car guys and gals that this is old news, but some folks forget the weight of the oil actually has to do with viscosity within a given temp range in Celsius. Also it should be said that FULL synthetic group 4 or 5 is the only oil to use now a days, no need to go near anything else...

OK im off the soap box

Try Royal Purple HPS.  Yes it is not as easily available as the street SAE version, but I am pretty sure you will like it . Amazon and Walmart both offer it.

If you are concerned about cold or hot extremes, get familiar with the viscosity and HT/HS properties of oils.  Remember the timing system will be affected by unnecessarily high oil pressures, so unless you monitor the engine closely with measurements, do not go too far afield.

I believe I will try Royal Purple HPS.  I just did a quick read and it sounds great.

Change your oil more often with a quality Full synthetic Group III or IV based Motor Oil while avoiding Media recommendations will keep your Cam phasers happpy! Z 
I forgot to mention Redline oil & Motorcraft FL-500S Filter.

I think people forget that proper viscosity selection is a product of operating temps. If you road race a SHO with no oil cooler you might need a 50 weight oil. I don't know that a 20 weight oil is thick enough to give adequate pressure after it's well used and sheared and in hot climates.

Viscosity is relative to temperature.

Viscosity discussions are usually pretty silly unless you have an oil pressure gauge....And if you don't have a gauge then the factory recommended is probably ideal unless you road race or operate in climates outside of what is in the owners manual.

Basically you want the THINNEST oil that provides PROPER OIL PRESSURE.

Oops I see the title is for best filter lol
