would a thick or thin 30 wt. make any real difference in day to day life?

I look at the viscosity to help fine tune oil selection. Some 5W-30's are thin and some are thick.... if I want better mileage I might look at thin, or I feel the engine needs more protection then thick might be better.

I think he's real busy with life outside the forum. I anticipate that he will update when he has time.

Sorry for going AWOL. Here's the latest version. I had to split it into two images to make it a bit more manageable.

I inquired about Shell rotella products and got this response:

Allan,

I show that typical values are 4.1 for Shell Rotella T Multigrade Oil SAE 15W-40 with Triple Protection Technology and 4.2 for Shell Rotella T Synthetic Oil SAE 5W-40.

Thank you for your interest in Shell Rotella Products!

They must be talking about HTHS

 

[M1Accord]

I like M1 and it is thin enough for me. It would be nice to get them in 5 or 10 gallon drum.

WOW!!! Great list. Here's the link to Andy's chart so you don't have to root thru 4 pages to find it.

I'm surprised that M1 10W30 and 5W30 didn't make the list.
M1 10W30 @40ºC 62cSt @100ºC 10.0cSt HTHS 3.14

M1 5W30 @40ºC 64.8cSt @100ºC 11.3cSt HTHS 3.09

 

[AndyH]

Here are both links (I had to split the chart in two):
http://andy.hedin.googlepages.com/Oil_Comparison1.gif
http://andy.hedin.googlepages.com/Oil_Comparison2.gif

Both M1 5W-30 and M1 10W-30 are in the chart...I think they were in the 2nd half of the chart so you must have missed them.

I posted this before... Motul's Specific LL-01 oil has become X-Max 5w-30. Same specs (HTHS is 3.5), but now certified to MB 229.3 - 229.5 and VW 502.00 - 505.00 as well.

I'm a newby.

What does HTHS stand for, is it better that the number is higher........or lower?

Thanks

High Temperature High Shear tells us how the oil will behave at temperature mostly in the bearings. Thicker is better, IMHO though mpg may suffer a little.

ACEA A3 ratings require HTHS of 3.5 or greater.
