Hey guys, I was just trying to find online where to buy my filters the cheapest. As I was looking I couldn't find anything that matches the part number of the oil filter I have now. I can't remember if I gave the guys at the truck shop this number or if they ran it for me and gave me this. The last two oil filters I have put on my truck are Fleetguard LF3349 but everything I find online shows that my truck takes a LF3894. Am I using the wrong filter? Will this hurt my truck? I also noticed that the LF3894 seems to be a little bit more money. Is this because its a "Strataport Oil Filter?" On this one website it shows the normal(not stratapore) filter to be LF3959? Help if you can! THANKS

So how come the LF3349 fits on my 24 valve? Am I hurting my engine by running this filter?

This is just me talking here but you have a very expensive engine there, don't always look for the cheapest. Look at what is best for the engine. Expensive oil filters are cheap compared to an engine overhaul.

The main difference is the 24 Valve filters use a stronger canister.
There were some reported problems with cold weather/thick oil, canister blowouts on early 24 valvers using the 12 valve filters.

LF3894 Stratopore is a better filter....use the best and you shouldnt have any problems
