Re: Oil Change

Follow up:

I finally read the SRT chat and there were 2 jems in there that are relevant to the oil discussion.

1. The old 0W-40 P/N was discontinued as it was the Mobil 1 oil so the service writer had half the story correct.

2. Using 5W-40 is not correct since the cam phasing (variable valve timing) is engineered to use the 0W-40 oil's overall higher flow rates. It could be argued that once the motor is up to temperature both oils would be working in the 40W extreme of their spec but based on the engineers response there is a difference even at the upper range even though they both meet the specifications of a 40W oil.

Just had oil changed, dealer charged $12.40 a quart for the new Penzoil 0W40....ouch. On a positive note...they knew exactly what to put in.

Re: Oil Change

The dealer here in Redding CA said they charge $8.00 a quart if you have it changed there. Also in 0W-40 the W stands for winter and has no rereance to the 40 just some food for thought. So for a good deal on an oil change bring your SRT to Redding

Yes, the W means winter or cold temp range and the higher number is the relative viscosity index of the oil at 100 degrees C but there is a range within those weights. A formulation of 0W-40 will flow faster at high temp than a 5W-40 or a 10W-40 even though they all meet the 40 high range. I doubt the engineer would have made the statement they did or taken the time to formulate a 0W-40 when their vendor, Penzoil, already had a good 5W-40 if there wasn't a performance advantage.

I disagree It means it is a 0 weight oil cold and has lube qualities of a 40 w oil when hot. Does not turn to the thickness of a 40 wt oil when hot. regards Lionel that's what I was taught in tech school, does it make sense to U that 50W oil means U can use it in winter in the cold of nova scotia or even to use a 20w 50 in the winter much too heavy and U would hear lots of valve train noise jus sayin & 8.00 is a super price for the oil wish I could get that they want 13 and change for a qt.
