Engine Oil and type?

[solidaxel]

How many quarts does the 5.3 truck hold with a filter.
I heard that the only filter to use was a A/C, because of some internal valving, is that true?
What weight oil is everyone using

Usually what that refers to is called an anti-drainback valve. Once the system has o.p, it helps prevent all the stuff in the oil passages from back-draining through the oil filter passage when the system gets shutoff. That way oil can only follow its correct path, so the engine has the benefit of still being oil bathed in between startup.

It helps with dry starts, and iirc it also helps with vehicles that have the filter mounted in a way that can cause the filter to run dry (Remotes).

This was something that I remember getting brought up as an issue on older high performance motors, but I'm not sure if on todays engines running synthetic oil it even matters much.

A/c isn't the only one, as WIX and others have also used it for a while. Certain part #'s don't have it, as certain vehicles don't benefit from it.
I try to avoid any super-cheapie filters, but I've used WIX, A/C, the Royal Purple brand, and a few others. There used to be big problems with fram, not sure how they are now.

6 quarts for a truck pan, Gen III truck engines take an AC PF46, All crosses to this filter have a Anti Drain Back Valve. 5W30 is the oil spec.

Thanks guys, I must have the wrong indicator stick as I think I put 7 qts before it registered, and I did put in a Wix.
I guess I will change filters that should take care of most of it !

Make sure the oil dipstick AND tube match the oil pan that you are using! Seems like each model is a little bit different and can give incorrect oil indications.....

Great, TBSS headers and a truck oil pan on a 5.3, the truck tube did not fit the headers, so I will try something different

[BR3W CITY]

You sure? The truck tube will fit, just don't bolt to to the head right away. Let it sag towards the next cylinder a little for clearance, and you can just tac a new bracket on.

I used tbss manifolds and the stock truck dip stick and tube fit

It will not work IF YOU bend it too far, and then try and straighten it out !!!!!!
