Ive been changing my oil at 4000 and some people at BITOG and a local mechanic friend, say thats too early (even if the car is mostly city driven about 60%) and to run the car for 10k on my oil. Im running 0w-40 Mobil One.

Also guys for my next oil change im thinking about switching to 5w-30 or 5w40 because the car burns a quite a bit of oil in the 4k interval. What would be a good candidate?

Should i continue using 0w-40?
OR Switch to:
Rotella t6 5w-40
Mobil one or Pennzoil 5w-30
Or mobil one 10w-40 <--- this is my 2nd option but think the 10 might be too thick for cold starts. Input?



Additional info car is a 2.8 with 105k. (partially the reason to switch oil is high miles)

Car is driven in texas so climate is always hot. And in summer temps will easily reach 100+

NA vehicles don't need to have their oil changed as much as turbocharged vehicles. But even then, people still say 3-5k intervals. I change mine every 5k, but I use the good stuff.

Exactly. 5-6k with the good stuff.

By the good stuff you mean audi approved?

whats your take on 10w-40?
i think this round ill try 6000k and possible send it to black stone and see how it performed.

I change mine every 5,000 or so with Castrol Syntec 5w40. It's vw/audi 502.00 approved. However, this last oil change I used Shell Rotella T6 5w40. I notice that my oil temp gauge reads higher on the highway than it ever did with Castrol.

I use Amsoil and it is "not" Audi approved. Along with that, I use Shell Rotella T6 for my back up (I order my Amsoil and there are occasions where it is not readily available for my dispense) which also is "not" Audi approved. As for the thicker oil, your mileage isn't that high. I'm at 142k and just installed my BT like a month ago. I even use 0w30 in the winter (5w40 in the summer), but will be switching to 5w30 all year round.

Yeah, I'd suggest you switch to Rotella T6 5W-40 and see if the oil usage calms down a bit. I would not recommend a 10k interval, 5k is plenty in my opinion. Rotella is not that expensive.

Have you checked for oil leaks? Valve covers, cam chain tensioner gaskets, cam plugs, etc? The oil from those areas almost never hits the ground because it is burned off by the exhaust heat.

Rotella T6 5W-40 for sure. people with oil consumption issues have noticed improvement with this stuff. a lot of the B5 S4 2.7 twin turbo guys run it too.

I will try rotella then! I had the leaks fixed with my timin belt job back at 89k and even then I didn't have a big issue with the leak. Just minor.

Ianwpb: if rotella makes the oil temp higher isn't that bad? The oil temps in the m1 is high as it is already. Reads about 225 on highway and reaches maybe 235 on higher speeds

I haven't noticed mine go up with Rotella. Oil Temp rides just fine.

If you want to really push the limits of your oil then just have it tested a few times as you get to the 5k, 7500 and 10k points. This way you will really know how far you can take it. As for my cars, I tend to run them to 7500 - 10k when running synthetic oil. The woman's Scion XA goes about 5k+ on normal oil which is when Scion says it should be changed. Doing it at 3k-4k is pretty much just wasting oil.

I run Motul 5w/40, oil changes every 3500 miles. Don't care that its not a turbo; I drive the crap out of it. I don't look at the amount of miles usually either; like clockwork, after about 3000 miles my V6 begins to eat oil like crazy. It won't burn any for the first 3k, then burn a quart in 500 miles. When I see if i have to top it off, it usually mean an oil change.

Car has 195,000 miles and spent the last 5 years climbing thousands of vertical feet a day. Still running strong.

There is absolutely no way I could go 7500 without a change; I would have topped up the entire capacity by then.

5w-40 Castrol Synthetic every 5k miles - look for the european formula - its very nice!

here's the blackstone oil analysis of Rotella T6 after 7,000 miles on a 2.7T (S4 motor):
