Oil filter Bosch or AMSOIL

If you are going to go with extended oil changes 10-20k miles you must use a high quality filter and if not a Group 3 Polyalphaolefin (PAO) oil, an actual full synthetic oil would be best. Mobil 1 and Castrol Syntec are not true synthetic they are (PAO) Group 3. Red-Line, Amsoil, and Royal Purple are the common true synthetics. If you paid less than $15-$20 a quart for oil it's not a true synthetic.

Your filter has to be high quality. Even then I would advise you change the filter and top off your oil at 8k-10k miles.

Oil filters that are able to go for extended runs are Wix, Napa Gold, and Bosch. Those are the 3 brands I trust for long term use. My truck with over 170k miles drives like it did over 13 years ago when I got it new.

Bosch oil filters. I used them to desludge 2 engines, and it CONSTANTLY keeps pulling more and more out. Only problem, they are black, so leak detection can be difficult if its in a tight spot.

I use Full Synth Royal Purple and a Bosch filter. I drive a 2002 S2K and the RP oil keeps the TCT noise in check.

royal purple, amsoil, k&N, mobil 1 extended, bosch long disance are good for more like 25k or 35k miles

5w50 castrol syntec and bosch filters what ever's on sale.

I run AMSoil European Blend (specifically for VW,AUDI, BMW,) and the filter as well. I change my oil around 4-5K depending on my driving during that time. My oil always comes out slightly 'browned' .... never dark.

Bosch 72174 = BIG

I have used both of these with great results.

I just use Bosch

I put in Pennzoil Platinum 10w-30 and a Bosch oil filter from autozone. My problem now is that whenever the oil gets up to operating temperature my oil pressure light goes on and stays on under 2400 rpms, anything above that and I'm good.
