Oil color is not a good gague to the "life" that's left in oil. Oil sample is the only way to tell. On my maxima, I routinely go 10,000 miles on the M1. Although the oil always looks black, the tests from Blackstone always shows that it is still in good condition.

Asura:

Based on your detailed info, I would stick with what is giving you good performance. Red line is always a top drawer recommendation.

I cannot explain why oil consumption went up with M1, but they do formulate at the lower end of the vis specs for a 10w30. But still, it is unusual....
You could try an oil change with the 5w40 Delvac to see if it reduces your oil consupmption further. if it does, you have a "loose" engine and might want to consider using RedLine or Delvac only. The RL maintains a stronger film strength at the ring/cylinder wall interface, reducing blowby (oil consumption) and increasing compression.

The RP thinning has been in enough cars to make it a real issue. I do not believe personally that their products are all they claim to be.

I picked up a case of Valvoline 10w30 MaxLife for my Subie 2.5L Forester and contacted the area LE rep who took my order for a case of LE 8130 10w30 and is looking for a broken case lot to grab a couple quarts of LE 607 90w for me. I have been unable to find the MaxLife engine additive anywhere locally. Folks carry the Valvoline SynPower additive but not the MaxLife.... go figure -

Again my thanks for your excellent and informative posts and responding to my PMs last week.

PS The Valvoline web site has rebates for MaxLife right now.

PPS No Pep Boys in South Dakota (re: your comment elsewhere that they were a source for MaxLife additive)

RR....Do you have any experience or an opinion of Marvel Mystery Oil? I did a search and came up blank on this one.

Did you try to look for the Max Life additive at Walmart? My walmart carries at at about $4.90 per bottle.

It appears that Valvoline has 3 engine oil additives.
Max Life Engine Protector
SynPower Engine Treatment
SynPower Oil Treatment

I wonder what the differences are?
Any info Road Rage?

RR, I recently switched to Amsoil 10W-40. I have noticed that the indicated peak operating temperatures have dropped by 20 degrees. While this may not be directly related to the oil alone, I am also observing that the Amsoil does not have the same 'heavy' throttle feeling as Redline in the same weight.

Since this thread popped up again, I recently bought some Valvoline MaxLife oil for my old Jeep. It was selling for around $2.50/qt and Valvoline was rebating about the same amount for up to 5 qts. It was a couple weeks ago so I don't know if the promotion is still going.

Keep in mind that Valvoline makes both a MaxLife oil, by the quart (ie 10W-30) and a MaxLife additive in a small bottle to add to whatever oil you are using. I used the additive and added it to my Mobil 1 10W-30.
