Pela Oil extractor
I tried to change the engine oil myself the other day, but I couldn't get the sump plug off (with every tool you can possibly think of). It got to the point of breaking a stainless steel spanner in the process.
Few members in the forum mentioned about accidental stripping of the sump plug or the container. That worried me a little so I decided to step back and think of an alternative way to remove the oil from the engine. I read some where about an oil extractor that is commonly used by many BMW and Benz dealers. I didn't know if it would work for my car, but I decided to give it a try anyway.
I bought a Pela oil extractor for $60AUS and I think it is one of the best car tool I've ever purchased in my life. Here's why. I was able to remove the oil from the engine in 10 mins. I didn't spill anything in the garage or under the bonnet. NO, I don't work for the Pela company. As a matter of fact, I was a little suspicious about the product before purchasing it. But since it only costed 2 figures, i decided to give it a go anyway.
I apologize for writing up an essay about this topic, but I hope I can help someone who faces the same misfortune...removing an over tightened sump plug is a b*tch and there's no doubt about that. Just remember that there's an alternative way of removing the oil from the engine.
