2003 Land rover Discovery 158,xxx miles

I have been reading threads on here about using the Mobil-1 301 oil filter. Amazon.com says that It doesn't fir my vehicle! Does it fit my vehicle???
Also I plan on putting Royal Purple 15w40 in it... That's good right?

 

Actually... since I am running conventional oil now and have been since I've had it. I should go with the conventional Rotella 15w40 so I dont have to replace every seal once the detergents clean it out from the synthetic huh?

 

But, I am still interested in what the best oil filter would be to use.

 

I run a Bosch oil filter from walmart with regular 5w-30. Should I be using something thicker such as 10w or 15w? I'm somewhere in 149k miles, I know for sure oil leak from the valve cover but I figure I'll tackle that with a complete rebuild one day. I know that didn't answer your question but the only engine noise I have is lifters? Under load using the 5w-30.

 

Luckily, I don't have any engine noise as of yet... I know that problems may soon be coming my way at 158k. I do have a slow leak somewhere and I figured from reading different threads on here that maybe going with a heavier weight would tone that down a bit. I replaced the front seal 3k miles ago. I'm not sure where its leaking from and its not a horrible leak. I try o stay on top of it and replace whats gone with lucas oil stabilizer for the heavier weight. I know that it has 5w40 in it right now from the shop that I used to go to. However... I do not go there anymore because they have caused more damage to the truck than they have fixed my issues. I recently had to have a new transmission put in because the mechanic left the drain plug finger tight. After getting the transmission put in my driver's side 02 sensor threw a code for no input... After replacing it, I found that when they took the exhaust off... they must have been tossing it around the shop because one side (of the o2 sensor) was crushed. (hence no input)
Needless to say, I am starting to do all the work myself and will have a lot of questions

 

Ah well hate you learned the hard way, but fixing yourself seems to help appreciate the rover more. Well I know the fun on the o2 sensors, still trying to figure them out. Well there's alot of people on here with lots of advice on any and everything on a rover.

 

The Mobil-1 301 fits but you needn't pay that premium price. Get a Wix 51515 (NAPA Gold 1515). Excellent filters for about 1/2 the price. Baldwin B2 is another excellent filter.

edit to correct filter PN typo

 

Valve covers can often be fixed by snugging down the loose bolts

Rotella 15w40 type oil and what anti said

 

any brand fullsize Ford fit

 

Yeah, any brand fits, but, like K&N air filters, just because they fit doesn't mean anyone should use them.
