            Absolutely!
            The world would be so boring if everyone agreed with everyone about everything.
            
            Good discussion. thank you.

   Yes, synthetic works much better. On high performance engines the difference is very noticable, but even on older low power engines, fully synthetic lubricants can increase efficiency and boost MPG and power.

      pfft ;-)
      
      Did a full flush + filter change on my Ferrari Mondial QV (a 25 year old car) then thrashed it around Mallory Park. The engine warmed up much much faster, was much more free revving, and pulled better at higher revs.
      
      After the track day, another flush + filter change, then stuck it on the dyno - an extra 8HP at the max rev range.
      
      Works for me ;-)

   Let's do some math. 8hp is just a tad more than 3% of 240hp. What is the error rate of your dyno? 3%? 5%?
   
   I don't argue synthetic oil does not give any improvement - it does decrease parasitic loses, which leads to slightly better mileage and power. But I wouldn't call this "very noticeable" - unless I just smoked something really good

   I'm synthetic all the way with my cars and my motorcycle!  My thoughts are that pure, fully synthetic oil extends the life and performance of a vehicle, so I'm all for it.
   
   I don't, however, change the synthetic oil every 3k miles.
   
   My choice of fully synthetic oil for cars: Mobil 1

         So there's no benefit to changing the oil more often than the manufacturer recommends?
         I beg to differ.
         While some cars will cope fine with extended drain intervals, others do not.
         
         Many manufacturers are reviewing their previously recommended oil change intervals downwards, due to the unexpectedly high proportion of sludge buildup (black death) in modern high performance engines of many makes of cars.
         
         If you think that frequent oil change intervals or synthetics are a waste of money - have a look at this.
         http://www.schleeter.com/oil-sludge.htm
         
         I've had SAAB's for ages - and currently have a 9-5. I use fully synthetic, and change it every 6,000 km.
         Maybe I'm paranoid - but I also have no sludge or turbo problems.

   Eric,
   
   What makes you thinking that you are smarter than the guys who designed your car and spent countless hours and millions of dollars testing it to make sure it will work as expected?
   
   Oh, and could you please link me to the source of information about manufacturers decreasing oil change intervals?

      Misha - The fact that millions of dollars and countless hours have been spent on something does not guarantee perfection, or even satisfactory performance. There's countless examples of this in the world - and not just in the automotive area.
      
      So - when clients of a car manufacturer (SAAB) experience a large number of engine failures whilst following the manufacturers oil change recommendations, this bear of very little brain tends to think that maybe there's something wrong.
      
      Especially when the manufacturer implements an engine replacement policy for cars up to 8 years old if it can be proved that the engine oil changes have been made as scheduled.
      
      That doesn't make me any smarter than the designers - only makes me think that maybe they got it wrong, and that it wouldn't hurt to change the oil a bit more often to avoid possible problems. Which is what I'm doing.
      
      As for providing links - all I can offer is that the topic has been discussed at length on various SAAB forums, and service agents have mentioned that SAAB, and other manufacturers have reviewed their oil change intervals downwards as a result of sludge related engine failures caused by not changing the oil often enough.
      
      Is this all just a conspiracy by service agents to get us to change our oil more often?
      
      Perhaps.
      
      And if so, then I'm just a gullible sucker aren't I.
      
      How about we do a little test then. I'll run my car at 25,000 km between oil changes, and if there's any problems you buy me a new engine. big_smile big_smile

      I know this wasn't directed to me, but - when Ferrari designed the Mondial QV, it was their first four valve per cylinder engine - cutting edge tech.
      
      Almost 30 years ago.
      
      Their choices in lubricants, brake pads, clutches, tyres - all were the best - almost 30 years ago. Technology has moved on, massively so. The metric Michelin TRX tyres were cutting edge, but they are rubbish compared to modern tyres.
      
      For modern vehicles I agree, but for older stuff you can definitely improve the running and reliability of the vehicle by *not* sticking to the manufacturer's recommendations.
      
      Another case in point - Toyota's older 2.2 turbo diesel suffers from blocked drainage channels, leading to overheating and cracked heads - a design flaw from Toyota (thanks guys!). Ignoring Toyota's guidelines and changing the oil more often - as well as using fully synthetic - reduces the chances of this happening.
      
      Lots of research in to this in the UK Estima owner's club.

   haha Misha, I bet your eating this up here!  Enjoy your promotional opportunities!
   
   Eric, I think you misunderstood me.  I'm not advocating that people change oil less than 3k miles.  Did you get that from me or from Misha's link?  Maybe I'm misunderstanding.
   
   When I said that I don't change the oil every 3k miles I was implying that I wait longer to change my fully synthetic oil because it's of a much higher quality.

      I was responding to Mischa's post.
      I agree with you that use of synthetic oil should enable me to do lots more miles before I should change it. Unfortunately, practical evidence suggests otherwise - for my current car, anyway.

      Agree. Much less anecdotal evidence and hearsay guarantee this
      
      Nothing here says that problems happen BECAUSE of oil - providing it was changed according to the schedule of course
      
      It does hurt your wallet. And environment.
      
      I'm sure it is. I would not call this "conspiracy" cause it sounds too dramatic - but yeah, service agents (they are called dealers in the US) are the ones who push this nonsense on consumers for obvious monetary reasons.
      
      I can't take your bet without at least looking at your car. However, providing your engine is in good shape, I am pretty much sure 20-25000 km is a reasonable interval for oil change currently. Applicable to modern cars and synthetic oils only

    I use AMOSOIL and have used it for years! I especially like the synthetic injector oil for my 2 stoke snowmobiles and jet skiis (waverunner). Not only does it burn cleaner, but the engine runs perfect and after many miles (hours of use too), I have had no problems and cleaner longer lasting spark plugs too! The recommended oil change with AMSOIL for vehicles is 25,000 miles!!! Sure saves time and money as well! Everyone has the own preference, just like I will never buy anything but GM vehicles, Polaris & Yamaha snowmobiles, and Yamaha Waverunners. Long term reliable running units!
