Oil filter AMSOIL or Wix

Wix. In 2003 Corolla and 2006 Rav4 + cheapest synthetic oil on sale every 5000km. Engine runs smoother. So smooth it feels like I can coast and maintain speed a lot of times. Which doesn't happen in my Subaru Outback with OEM filter and Mobil1 synthetic.

I use Valvoline NextGen high mileage synthetic blend 5w30 in my 1998 Tahoe w/ 161k miles. I usually use ACDelco or Wix filters. Depending on how much highway/city driving I do I change between 3k-6k (manual says 3k for city, 7k for highway) and five quarts go in, five quarts always come out :D. I used Valvoline full synthetic high mileage for about three changes in a row, but decided it probably wasn't worth the cost on such a high mileage, non performance engine. Plus, I wanted to use the NextGen when it came out. So far, I'm impressed with the recycled oil.

wix filters , and shell rottela 15w-40 still a new motor with just 1500+ miles so soon i will go to syn

Clean Throttle Body, Clean MAF, Change air-filter if needed (manual recommends every two years unless you live in a dusty environment), change fuel filter ( depending on mileage or time. I do mine every two or three years, if it has never been done, do it). Run a good injector cleaner through (Chevron Techron if you can find it)the fuel system, then run another tank of gas through, and then do an oil change with synthetic oil and a good quality oil filter (Wix are good (napa) or any of the OE/OEM German filters like mann, mahle or bosch.).

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.

I run the 5w30 Amsoil 15,000 mile stuff in our 1.8t... it gets changed once a year. Every 4 months i put a new filter on it and top it off. The samples i've sent in and been returned all looked good if the car is just a driver with some occasional track time i wouldn't sweat running Amsoil or any other really good synthetic 10k or more.

My local NAPA always has my oil filter in stock. It's a good quality WIX filter.

amsoil makes a filter that filters better than stock

I just run Amsoil for 13000k, and change a filter in between. Seems to work fine for me.. and it's preety cheap if you buy the stuff from Amsoil!!

i have 107000 on my wolfie now amsoil 10-30 and their filter cleans better than stockers i change at 10000 miles no problem change sooner for short trips especially in winter redline mt 90 in tranny
