Oil filter VALVOLINE or Hengst

I use Valvoline advanced full synthetic or quaker state full synthetic, and those oils seem to hold up very well (ive tried plenty of different brands) and you can buy it anywhere for top off oil. I have been interested in using liquimoly though. For filters, i use k&n, wix, or the nissan oem.

It’s easy peasy to DIY at every OCI (5k mi or 6 mos whichever comes first, 2014 Mazda6 Touring 6MT). Been doing it, for decades (various makes; at times with an oil boy vacuum fluid extractor). Will be changing mine tomorrow. This time, will try Kirkland 0W20, with a German Hengst oil filter (identical dimensions/specs Made in Japan OEM Mazda PE01-14-302) plus Lubro Moly MoS2 (molybdenum).

Oil service has been done every 5K since then using Liqui Moly Molygen Full Synthetic 5W-40 and Hengst filters.

Go on Groupon and look for shops in your area. I get coupons for Valvoline and they’ve always been good to me. I save a good bit as well!

I just put Valvoline full synthetic high mileage 5w-20 with a motorcraft filter in my 2011, and it runs so smooth now. I used to have some noise on startup but nothing now.

My E550 gets M1 0W40 every 5k, with a new fleece Hengst filter. I don't drive it hard until I see past 80C on the water temp (I don't have an oil temp gauge- only the E63s do). Basically the same procedure I use on my S54 BMWs, and every performance car I've ever owned

$0 because e-Tron however, on the A5 2.0T; I’m paying $50 for oil (Valvoline full synth) and $16 for the oil filter…but I own all the tools and use my employee discount.

I do the oil every 5k on both and use liquid moly 5w40 and a hengst filter.

The "valvoline" brand ones are pretty shit.

since vw started using the synthetic material i am very fond of using oem. ive never seen the synthetic material deteriorate or crush in the housing between oil changes. ive also seen the plastic on those types of hengst filters break apart and that scares me to use.
