    Oil testing and results

    There isn't really much out there as far as motor oil tests outside of the Amsoil ones. Kind of disappointing. There is this <a href="" target="_blank">sportrider</a> motorcycle oil test where they included a couple of auto oils.

    Toyota 0w20, 6644 miles, 2006 Civic

    I'm thinking 7% is an error too -- like maybe a 2 got transcribed to a 7 somewhere along the line. If it was really was 7%, the oil when drained should have had a pretty strong gasoline smell.

    Consensus is that a little over full is OK?

    Engines always have a built in safety margin of probably close to a liter or more. They have to. One has to expect that the sump will be overfilled a little at least sometimes. No way even 1/2 liter of extra oil should be able to cause any real problems. Over the years I have overfilled the...

    Help me choose oil in Australia

    I think Mobil 1 TDT 5W-40 is Mobil's best motor oil. This should be readily available in Australia. It would be on my short list for the best motor oil out there.

    Real Viscosity

    Slight correction. I believe there is only one reference oil for the fuel economy test, but the different grades have to beat that one reference oil by different amounts. It's been a while since I looked at he API/ILSAC spec;s <img src="/forums/graemlins/smile.gif" alt="smile" title="smile"...

    Help me in my Oil Debate

    I would lean towards a 40 weigh for a turbo engine run in a hot environment, or a A3 type 30 weight with a HTHS of 3.5 or greater. But almost all the 30 weight oils here in North America are energy saving so their typically < 3.5 HTHS. If you're going to go with a 40 weigh I don't see the need...
