What Oil to use?M1, Castro synt? or other

[vath2001]

FYI... I Just did a Mobil 1 oil change, 10w30. In retrospec, I would have gone to 10w40. I am not sure but it seems to runs a little hotter now, compared to the old oil (which I have no way of knowing the weight). But now I am driving in the summer compared to the spring.

I bought my oil from Meijers at $19.99 a gal (on sale), and the quart cost me $5.49, I got the filter from the Zone. I would recommend getting the filter wrench from the Zone at the same time.

My thoughts on oil... I run the the TL and Chevy on whatever is on sale (they have 135k and 100k respectively). I ran my old Civic SI on whatever was on sale... when I traded that away it had 190k. You could argue that running better oil makes the engine last longer... or I would argue that doing oil changes at the prescribed interval it more important than the label on the bottle. But what do I know.. I can show only 425k of research.

Red Line is a class 5 full synthetic made with Polyolesters.

To my mind, it is hands down the best.

IMO.

I bought a case of Redline 0W-40 last week for $136 shipped.

I've been using M1 0W-40 without any problems since I've had my car. However, all of the info from Flat 6 and LN got my attention. I only drive 2,500 - 3,000 miles per year so I change the oil annually which makes the cost less of an issue for me.

Well the saga continues. I am set to put some CAstrol syntec, or mobile 1 in Box. Problem is nobody has any xxW40. its all xxW30. I know better to use the latter(30 is bad).

My question is they do have M1 10W40 (highmilage) AND 5W40 (turbo diesel truck) Can I use either one of these?
My local Oreilleys has buy 4 get 5th for free(upto two free) on Mobile 1. This is perfect for me.

Honestly Vath2001, What I have read ,and its a lot, you need to stay away from xxW30. Most experts warn never to use it. Now there is a cure, drain out 2 or 3 quarts and add xxW50. It gives it a xxW40 average. Some guy on another site posted he used the same as you and the "experts" told him to get it out as soon as possible. They are more concerned about the weight rather than the brand.

PS I saw the miejers add also for a gallon of M1 for $19.99 Damn nice price.
