Engine oil Mobil or Lucas

I personally use Mobil 1. They all do basically the same thing if you're changing it often enough. I change mine between 3-5k miles typically.

I used the mobile advanced fuel economy, I live in a pretty mild climate. I have seen lots of people swear by asmoil it's supposed to be good.

From my own experiences, M1 is excellent. Been putting it in my 30 year old Celica for 7 years, gotten 160k miles out of it, 320k miles on the original motor in total. My buddy’s Corolla had a bad timing chain slap on startup, went dead silent ever since swapping him over to M1. I just stick to what I know.

I’ve used Mobile 1 full synthetic for years, most manufacturers warranty it.

i have a 5qt of Mobil 1 sitting around in case i ever need to take it in for warranty work.

I run Mobil 1 15w50 in Colorado in my 1.8 8v 85 GTi. For camshaft insurance I add a zinc additive at oil change time.

I use Mobil 1 15W50 zddp conent is higher than regular oil.

Used Mobil 1 in all my Toyotas for the last 20 years. My dad's Scion xB is close to 400k miles running strong.

I typically use whatever is cheapest and proven oils for all my cars. I have an '08 2.5 and have been using T6 5w40, they typically run coupons for them for $20 or 25.00 for the gallon jug. No, it doesn't get VW's official stamp of approval but it seems to do pretty well in this application and seems quite popular amongst various other makes especially Euro cars that require a 40wt oil. Quite honestly, I'm pretty sure you can run a quality 5W30 in this motor, it is not anything special. I've run M1 0W-40 and although it has the VW spec labeled on it, my car always had a faint tick coming from the valve cover area (lifter?) when warm. It never did this with the T6 oil in it.

I used 0-40 mobil 1. It turned out pretty bad for me, I ended up using more oil than I ever had before. The car smelled like a friggin chainsaw with that stuff. The engine only had like 100k on it, but the blowby was horrible with 0-40. This was just my experience. I use mobil 10-40 now and no problems so far.
