Oil change mileage and recommended type

Hi guys just picked up a 1988 911 cabriolet with 98,000 on it. I was wondering how often does the group recommend to change the oil and what weight of oil is generally recommended. Also As a diyer waht ramps do you recommend to get the car up to perform this service.

Thanks

You'll have to search as oil brand and weight are frequent topics. I forget what constitutes an old engine, but I think 88 is okay with a full synthetic like Castrol Syntec.. I use 5W-40, but not sure about your year car.

Most would recommend changing oil & filter once a year or every 5-6000 miles. whichever comes first. Much more for track car.

I recommend Brad Penn dinosaur oil in 20W-50 for oldsters like my 914.

Ramps are not good in most cases as you want the car level. For my Boxster I've used trailer ramps, 2X10s, and jacked the car to get at filter/drain plug. You have to unjack the car to get all the oil out and re-raised to install plug. . Use a jack stand whilst under the car.

My 70 911 could be changed by crawling under from the rear. Just use a thin pan. Use a fresh crush ring on the drain plug. And a new gasket if you remove the strainer, which I'd do for first change..
