What type of racing oil and Synthetic Lubricants Do you use
Absolutely!
The world would be so boring if everyone agreed with everyone about everything.
Good discussion. thank you.
What are you smoking, Finance? I want some
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 goodLOL I can't resist another shameless self-promotion
http://www.funandsafedriving.com/ftopict-39.htmlI can't remember ever changing the oil in my 15-year-old Renault Clio and don't have any sludge or turbo problems either
So - this would be a 15 year old car that you bought last month perhaps ???
Misha,
The fact that millions of dollars and countless hours have been spent on something does not guarantee perfection, or even satisfactory performance. I'm sure you'd be aware of countless examples of this.
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 using the oil of your choice, and if there's any problems you buy me a new engine.

Eric G.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!
