now here the age old question, ive always ran normal non-synthetic blend oil. can i now start with synthetic? i talked to my old mechanic and he said it wouldnt hurt. but theres a reason hes my old mechanic so i cant really take his word on anything.

also besides WIX, any reccomended filters? i heard frams trash, purolator isnt bad. ive had napa gold filter in mine by my mechanic

 

Napa gold and wix should be the same. Just stay away from fram. If you want you could start by running semi-synthetic for a few changes then go to synthetic. I only use wix or napa gold now myself, good quality and decent price.

 

FWIW Ive been on a Valvoline max life kick lately. 5 QTS and a bosch filter is usually on sale at Autozoo for like $25... Run it in the blazer and my girls cherokee. I save the synthetic stuff for my Camaro

 

yea that sounds like a good idea, i just looked at a fram cut down the middle, just looks cheap. anyone have experience with purolator?

 

i use purolator filters never had a problem with them but i've never had a problem with frams either but i switched just in case

 

You can go back and forth between synthetic and non... you can even mix. There will be no harm done.. its all a myth.

Like Jason said. Napa Filters are made by WIX... so if you got a napa gold filter, you have a WIX filter. The only difference for example, your filter is 3518... napa it would be 518... Just missing the first number.

 

That is very good to know. My last question is with synthetic...I heard if you have a leak which I do somewhere but its slow. Will putting synthetic in make it leak worse? I saw a video on how synthetic can seep into places where usually conventional doesn't

 

If you have a leak, you have a leak. It will only get worse either way

 

yea that makes sense...apparently my old mechanic was putting 5 in, but you guys say start with 4-4.5, could him overfilling it be a reason its leaking? because it looks like it could be from the top of the pan (maybe), but the oil actually drips from the rubber plugs right near the plug. anything above i cant see, but i heard also the pan bolts sometime just need to be tighetened, what size and how many are there

 

I use Mobile 1 Highmileage 5w-30 with the Mobile 1 oil filter. I have used the Puralator Pure One filter before.
