I changed the oil every 5k and after replacing the gearbox input shaft bearing, the engine started to 'burn' about one quart every 3-4k that ended being a broken AOS accordion hose making a mess everywhere...

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

POST 1 / ORIGINAL POSTEROriginal post

I was wondering how often do people have to add oil between oil changes. Things that might be useful are model year, s vs base, how many miles on car, how many months between oil change, how many miles between oil change, do you have to add oil between oil changes - how much and how often/how many mile. So here it goes: 2000 base Boxster with 62500 miles, change oil every 6 months about 2000 miles between oil changes, don't need to add any oil, oil level doesn't drop much at all maybe one notch at most or not at all on digital readout. Used to change yearly until IMS update, never have had to add oil. Have had car for coming up to 16 years.

POST 2Original post

Ditto, except it's a 2003 S and I change oil once a year (DT 40), roughly every 3-4,000 miles.

POST 3Original post

2001 S with 27,000 miles. Oil changed yearly (January 1) JG DT40. No added oil.

POST 4Original post

I am not sure you'll find anyone who runs their oil long enough to have the car burn any. I change mine when I put it away and when I take it back out. Never had to add any.

POST 5Original post

1999 Boxster oil change every 5K miles or six months. Never have to add.

POST 6Original post

5k between oil changes, about 2 per year lots of spirited back road driving, multiple AX and track days Generally no oil added, maybe a few ounces at the track

POST 7Original post

Change oil every 2-3 months (every 3 race weekends). Mobil 1 High Mileage. Oil level never changes. 90K mile engine from salvage yard. Engine driven to/at redline continuously for 2-3 hours per weekend.

POST 8Original post

It's amazing reading about earlier cars with so little mileage... Mine it's an '07 with 87k + on the clock.. come on guys get out and enjoy your cars :-) I changed the oil every 5k and after replacing the gearbox input shaft bearing, the engine started to 'burn' about one quart every 3-4k that ended being a broken AOS accordion hose making a mess everywhere... After replacing the accordion hose no more 'oil burning'... LOL

POST 9Original post

1st oil change after a new IMS coming up. Every 5k. Just last week it gave me a low oil warning on the OBC. It was just touching the tip of the dip stick. I know it was dead center when I filled after the last change after car warmed up. Also did LN spin on adapter and magnetic plug 141k miles.

POST 10Original post

99, 2.5l, 55k on engine. Oil change every 5k, one time after 10k, never had to add any. For the past two years it was a daily driver. 60 mile round trip. Mostly regular driving with some foot in it on a regular basis as well.

POST 11Original post

'99 2.5L daily driver w/ 95k miles. I change the oil every 5k miles, and I have never had to add oil between changes.

POST 12Original post

That's good to hear these engines don't seem to burn oil. I haven't changed mine yet, I just bought it last July and only put on maybe 200 miles if that. I'll probably change it next spring, the car has around 111,500 miles on it and it's a 99 with a 2.5 ltr.

POST 13Original post

I have a 1999 Boxster. I've had it since 2009. I purchased it with 104,000 miles. I now have 262,000 miles on it and I change the oil & filter every 10,000 miles. I use either Mobil 1 or Royal Purple. I have never had to add oil between oil changes. The IMS is original. MNC-I

POST 14Original post

2000S. Owned for last 7+ years. Purhased at 76K miles. Now has 128.5K. I added 1 liter of oil once. I change oil ~8 months or so, which equates to 3 or 4 thousand miles. No leaks, No IMS work done.

POST 15Original post

Quotes source post: 471784

If you're gonna store the car over the winter, at least change it before storage. Otherwise your bearing will be sitting in dirty oil all winter. I change it in the fall before storage and again in the spring when I take it out.

POST 16Original post

'98 base. 45K when purchased 2 years ago. 51K now. Annual oil change is the plan. No adding necessary.

POST 17Original post

2000 BoxS. Purchased in 06 with 60k. Now at 180k. OC every 5k, Castrol Edge. Nothing added between OC 1999 Carrera 4. Purchased in 13 with 50k, now at 112k. OC every 5k, Castrol Edge. 1qt between OC.

POST 19Original post

The only time I ever had to add oil was when I over tightened my LN magnetic oil drain plug and it leaked. 98 2.5 base 114,114 miles

POST 20Original post

I've never had to add a drop of oil between changes on either of mine. Average 5,000-6,000 miles between changes. Weekender: 1999, oil change annually, 98,000 miles Daily Driver: 1999, oil change every 8 weeks, 154,000 miles
