Oil Change every 15k miles?

[KRAM36]

Glad to see 5k is what people are doing normally. My last oil change was perfect (knock on wood) nothing stuck the magnetic drain plug and no debris found in the filter.

I change mine every 7k using Mobil1 15 / 50. I live in Northern Calif. I use Synthetic oil because it doesn't break down as fast as non synthetic.

If your changing your oil every 3k to 5k, use a good non synthetic oil and save yourself a little $.

Your comments/opinions especially on using Mobil1 15/ 50 would be much appreciated.

Thanks!

eacall0986,

I normally use Mobil 1 10W40 high mileage, but decided to switch to Mobil 1 15W50.

I can purchase both at Walmart for about $25.00 in a 5 quart jug.

I wish Mobil 1 would offer its extended (good for up to 15,000 miles) oil in either the 10W40 or 15W50 weight.

Since my 99 Boxster has over 233000 miles, if the engine goes bad I'll just part it out and move up to that 996 I been wanting since day one.

Just my two-cents.

Wow 233k congrats on your '99 impressive! Have to ask the question, any IMS replacements done?
I have a 2001 Boxster S Manual 6 speed with 80K and will need to decide at the time I need a new clutch to have it done or not.

Going to my local Walmart for Mobil 1 as soon as I get a chance. I'm also going to be replacing the transmission fluid. Thinking of using a manual pump from the fill opening to remove the old transmission fluid instead of having to remove the bottom cover and the aluminum brace just to get to the drain. Hopefully I can get it all doing it this way. Advise or thoughts if any?

eacallo986,

I purchased the car in 2009 with 104,000 miles. I don't know how many people owned the car before me, but I would guess it has the original IMS.

From what I've read, a car with at least 50,000 miles would have had an IMS failure by now. Personally if I were you, and I am not you, I would not change out my IMS. However, if replacing it eliminates your worries then go ahead and do it.

Thanks for sharing your story and info. Always makes me feel good to hear from owners with plenty of mile on their car and have had no problems with the IMS.
