and what kind of oil and weight do you use ?
synthetic ?

 

Once a year. I only put on about 4k miles a year, so I take it in to the dealer for a once a year lookover/oil change. They use Mobil 1 synthetic.

 

after every driving event, which for me is monthly or bi-weekly.
dont know recommendations for guys who dont really drive there car much, guess if you use synthetic and dont drive much every 15k or yearly.

Mobile 1

 

ill probably put around 800 miles/month on my car, but i will be driving it hard ...
what do you suggest tom ?

 

Steve, may I suggest you check out this:

Oil Tech

And ask your question on this forum:

Bob the Oil Guy

It seems that some of the reading suggests it is not actually good to change your oil too often. When you do change it I suggest you:
1. send the oil in for analysis
2. cut open the filter and inspect it for particles and such.

My suggestion is to change it at least once in the spring (as cold temperatures may effect additives in the synthetic...and then every 5000 mile..FWIW.

 

Once a year or 10k miles (whichever comes 1st).
Mobil 1 0W-40

 

once every 5k miles mobil 1 0w-40

 

5k miles with Mobil 1.
Going to try Mobil 1 5W40 during the summer.

 

About every 5000 mi, Royal Purple, it works in the race car, it will work in the Porsche

 

thanks guys
so , stick with 0w 40 in NYC aswell ?

 

Every 5k should be fine.

 

why is the dealer telling me to change it every 20,000 miles ? lol

 

I go every 3k with Mobil 1

 

Wow 20k..Maybe they are trying to get you to buy a new car soon?
Good thing about burning oil in these cars => replenish with fresh oil as you top it up.. but still. 20k is extreme. I think 5K miles is a good figure if you drive it regularly, or every 6 months whichever comes first.
