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

[jmatta]

FWIW, I use Royal Purple 10W40 in my seven year old S with just under 16k miles. Change it once a year, which equates to 2500 to 3000 miles. I've read very good reviews for Castrol Syntec 10W40 and at half the price, would be tempted to try it.

After reading and seeing the failures on both LN and Flat Sixes' sites, there is no way I'd use Mobil 1 0W40.

To each their own...that's why there are so many different beers out there...everyone has their own tastes.

I have heard royal puple has a loyal following. I am leaning towards castro syntec because I haven't heard anything bad about it. I see you live in the Chicago area(gotta love Genos east pizza ). anyways, do you drive your car in the winter? I am guessing not due to the low miles on your Box(16k). I plan on racking up quite a few miles as i just love to road trip with it. I plan to change the oil 1 1/2 to 2 times a year(yeah I know 1 1/2 its an average ).

I appreciate the input, as that is why I started the thread. Since all the doubts about M1 are recent, it raised some concern. I just would rather be safe than sorry. I guess the only way to find out if the engine failures and Mobile 1 are true is if I had one. Not a rosy scenerio for me.

Its funny everbody gives a differnt story ,one says royal purple is the best next guy says its sucks ,they used to say ams oil was the best in jet skis ,bikes, cars, etc now the same people say not to run it at all not even in your lawn mower ,same with lucas oil everbody said it was the best when it first came out or became popular now they say it sucks, now royal purple is fairly new or popular now they say it is the best ,next year they will say not to use it ,and there will be some fancy name new oil on the market they will say to use ,I have always heard you can not go wrong with mobil 1 my 98 box has it and has never had a problem and it is driven hard and has 88 k on it ,I have never heard any thing bad about castrol and run that in my 914

I agree RD its the flavor of the month. I am looking more of what to stay away. I mean I could run regular 10w40 oil from jiffy lube and never have a problem. Its a pretty whacked subject. Everytime i do a search I come up with negative stuff on any motor oil. Just put the pharase "don't use" in front of the oil. Ie the link below is the latest.

Good Frickin Grief. I think I might just flip a coin!! hell if my engine does blow, then I can put a 3.8 in it for only $26,000.

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.

Where's the best place to buy Redline?

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.
