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

Hey I wanted to get some insight on a few things. I'm going to get my oil changed (1st time since owning it). The last oil change looks like a couple months ago, the coolant was changed about a year or so ago from what paperwork says. when should I get the coolant drained and have the old coolant drained & new coolant put in. Any suggestions. what oil is good to use?? I know you use extended life coolant, but which one, I saw so many out there. I do live in New York if that makes a difference.

POST 2Original post

Welcome. I'm not an expert like many of the folks on the forum but can offer this: the shop I take my '98 for service uses Amsoil. Haven't had to change the coolant yet. Others can help with suggestions for that. Use the search feature and you'll find a great deal of opinion, fact, spirited debate and otherwise regarding engine oil.

POST 3Original post

OMG no! No oil questions please! Use the search function and you will quickly realize there is no right answer for which oil to use. None.

POST 4Original post

Hello and welcome. If the coolant was changed last yr, there's no need to change it soon. If it's pink, the previous owner used Porsche coolant, which has a "lifetime" shelf life. Unfortunately, the water pump only lasts 4-6 yrs and you'll have to change coolant when the water pump gives up the ghost. Be sure it's good for those cold NY winter nights and you should be fine for several yrs. If you don't know what brand it is and it's low, add distilled water to bring it up to the proper level. Then check how strong it is with an antifreeze tester. What oil to use will spark a holy war, as everyone has a favorite. Use Mobil 1 for this change and do your own research for the next one. There are plenty of threads on the topic

POST 6Original post

I'd go with Oil of Olay if I were you. It has anti-aging properties, plus it will hide the wrinkles in your convertible top. I would also learn to click on this button: It can save you from the embarrassment of asking a question that has already been asked 100's of times and discussed endlessly. Welcome to the forum.

Also note that if you mix the Porsche coolant with many other coolants (yellow or green) it turns into pink jelly. Always do a thorough flush if you are not certain. Oil? I just use what ever is on sale that week. Here's a post on Rennlist that has a list of 100+ oils you can use: New (2015) list of Porsche approved (a40) oils - and a strange change ... - Rennlist Discussion Forums I'm seriously considering this for my next change. If it's good enough for my 1986 Ford diesel, it should be fine for my '99 Porsche. Right? Here's a good read: http://986forum.com/forums/performance-technical-chat/56373-yet-another-oil-thread-%2Acaution%2A-science-content.html

POST 8Original post

As you can see, there are lots of opinions on oil. Do some reading and decide what you'd like to use. Regardless, 5-7k mile oil changes are as important as what oil you've decided to run. "Lifetime' coolant is used in your car. Personally, I changed my coolant at about 95K miles. I splurged and purchased the Porsche coolant at $30/gallon, as it took any angst out of the decision and I may not ever have to do it again.

POST 9Original post

Can't go wrong with mobil1 it is what porsche recommends, I always liked it since it was first introduced.

POST 10Original post

Have used Mobil 1 0w40, currently on Castrol Syntec 5w40, and going with Lubro Moly on my next change. For coolant, running Zerex G-05 (Mercedes-Benz formula for aluminum engines). Also, Pentosin G12/G12+ (VW/Audi coolant) is favored too.

You are correct. All defined by the container's sticker and fancy 3D motion simulations of rev'ing engines on TV to me lolll If I had to recommend oil to anyone, for a Porsche car anyway, I'd say stick to what they recommend (Mobil 1, 0-40). The type/viscosity have been tested in their labs more than once I'd like to think. Tested for chemical stability with the type of steel & aluminum grades, carbons/silicons, and other composites your engine is made of (harsh conditions tested also). Pressure that oil makes on vital high speed components have also been tested, by Porsche Eng. Those same guys that some here thinks, don't know half of what they are doing.

^^^ This ^^^ Don't believe the hype of 10K mi oil changes. Best ins you can get for your engine is frequent changes. I do mine between 4-5K mi.

POST 13Original post

Quotes source post: 504062

Uhmmmm...i call bull**************** on the pink jelly remark. I put green stuff that was stated to be compatible with all coolants and it really was compatible with all coolants. no pink jelly....I use whatever synthetic is on sale when I go in for oil. I don't use 0W40 or 0W50. i use 5W or 10W and synthetic. I have been told that synthetic is more tolerant of high temperatures and breaks down at higher temperatures so its worth the expense when pushing the engine hard for sure.

POST 14Original post

Buy the magnetic drain plug before your oil change. Change the air filter and the drive belt if needed . Its cheap and a good ideal.

POST 15Original post

Quotes source post: 504278

So you got lucky. But it can and does happen, so maybe do your homework before you call bull. Might save you from looking kinda stupid.

POST 16Original post

Same as oil choice. Coolants have different levels of PH (acid), Silicates, Sulphates, Borates and other additives. Each manufacturer specifies a formulation suitable for the metals in the engine, rubber hoses, seals etc. Nothing to do with whether it mix, perform better, "price", or anything like that (geez guys). Since I don;t own a test lab, and know clap about coolants and the materials used in our engine, I am going to stick to what Porsche Eng recommends

POST 17Original post

Quotes source post: 504278

Not every coolant that is mixed with Porsche coolant will cause a problem, but some will. It is real, so why take the chance? Do a flush if you are not sure. Here's a water pump that I pulled from a failed 2.7l engine : The pink gel was also in the coolant passages of the engine and no doubt, the rest of the cooling system. Here's a little reading on the subject if you are interested, click the quoted text for the link: Pedro: JFP in PA: Lots more info out there if you bother to search before calling BS. :dance:

POST 18Original post

Straight answers to simple questions; Use Mobil 1 in a temperature appropriate weight for your location Change the coolant every 3 -5 years (or whenever you change the water pump) and use the Porsche OEM coolant.

POST 19Original post

Would be nice if one of you pro could do a quick but concise write-up and "Sticky" this on the forum. A place where we can redirect ppl too instead of asking them to search. Or just copy what they did on RL and sticky here, dunno I have to agree with Giller, pretty regular question and often leads to 'cosmetic for women' type arguments.

POST 20Original post

I actually might be in the best possible position to say that my 1997 Porsche Boxster always had Mobil 1 0-40 every 2,500km (overkill I know, waste possibly) and new oil filter every 5,000k. New pink coolant and distilled water every 4~5 years. ATF change twice (50k). 20 years old car and literally nothing leaks on the thing (original coolant cap, go figure). RMS is fine, no rad damages or hose leaks, original water pump, no oil dripping. Just nowhere, zero. Approaching 100,000 km, kept indoor 90% of the time.

This is a source reference. Confirm exact model applicability in the original material.
