Don't mean to start a war, but is there harm in going 0w to 5w?
Like the title says, I wanna change over from 0w to 5w40 for the summer in Florida, is there any harm in doing so in my e55? It's got almost 96k on the dash, I remember reading you don't want to change weight on older cars... the oil I want to use is Liqui Moly 5w 40 instead of Castrol 0w 40 (what I use now)
there is also liqui moly 5w 40 top tec 4100, I'm confused about which one is better...
It's just that it's hot as **** in Florida so I want maximum protection during the summer, I plan on driving the car daily.

I ran rotella a couple changes back, supposedly it cleans crud out of the engine, but I haven't noticed a difference. I'm back on mobil 1 now because of the rebate.

Some info that I hope will help.
5w-40 has a better additive pack than 0w-40.
Any "0" weight oil was designed for emissions on engine start up. That is the main reason. Period! The tighter the laws got ...the more ways where needed to meet the standard"s and zero oil's fulfill that. Temperature plays a role as well but lets not get to far in to this.
Everyone thinks Mobil One is the "god" of oils because it is recommended by many auto manufacturers. Fact is THEY won the bid to use there oil.
This is not my opinion and comes from an oil engineer who created many oil blends and was working with these companies.
Was told Rotella and Liqui Molly as two of the best oils out there tested and used.
Also switching from one oil to another will make no difference. Your engine is mechanical and just doesn't know lol.
I can not tell you how many engines I tore down after dyno thrashing to see what the bearings looked like afterwards and every brand of oil was used over the years.
I can tell you a few of the worst I ever saw after race tear downs but dont want to go down that road.
And by the way "full synthetic" is not 100%. The supreme court ruled years ago that oil company's only need something like 23% to be considered "full". Semi is even less.This is what I am schooled on....this is what I know.

So this will do?
Odd that it doesn't come in a 5 liter package, and very annoying because now I need 2 jugs and another quart.
Wait that one is for diesel....

That oil works very well.
I can also tell you that you can google " what's the best motor oil" and come up with many hits with people claiming how great one oil is over another.There basis is just like when some one does a mod to there 55 and swears how great it worked and can back up there claims because now the "traction control light" blinks more than before so it must be good.
Oil is the same way to people. The engine may get louder or more quiet but thats about all you will notice most of the time.......unless you do tear downs/inspections and oil test's to really see whats going on.
Additives are the same way. There are some real snake oils out there and one that I personally tested one year at the track was a total disaster ,rear diff , trans and engine. I was sold on it and I really believed the product to be the beast thing since sliced bread and seemed to be when pouring it into the engine......NOT !!

So do you believe in any additives? Personally I've had a good response from Technron (I mean it changed the *** out my car immediately) and Ceratec in my older Merc/any older car we have had.
Also when i went to Lokey Mercedes nearby I saw posters for BG's MOA and 44k (I know about 44k, proven to clean fuel system, but the oil additive and engine flush... I didn't think a Mercedes dealer would advertise that) so now I'm not too sure what to think
A lot of BMW owners praise ceratec/mos2, and some C63 (or 32?? Not sure) praised ceratec for curing lifter noise. It is impossible to tell what's real and what's not anymore. Sometimes I wish I went to work for an actual oil company instead of fracking so I can learn the secrets of lubrication, there's always money in lube.

I was really hyped about the Shell oil because it's a lot cheaper but it is what it is.

Walmart and autozone stock this stuff too, probably cheaper than amazon, I remeber paying 18$ a jug.

Do I believe ? No, not any more. Listen I am no expert and people will argue there points of facts with me and thats fine....I love to learn.
I had access to a dyno to do what ever I wanted. Almost every part I bought was Dynoed. Headers back to back runs. Camshafts, H- pipes,x pipes, no cats with cats, oil additive, octane boosters {wrote a magazine article on Torco boosters with fantastic results.
Did Dyno tests on how much a supercharger {Paxton Novi 2000} robbed as far as horse power goes. Again back to back, car never left the dyno. LOL they would not publish those results !!! LOL
Im rambling now, crap day at work, sorry !!

I just ordered EC mids from shardul, going to install them next week when they get here. I'm straight piped up to the mufflers, how do you think this will affect my IAT's?
Currently as far as cooling goes i have MB coolant, a bottle of purple ice, and a 010. I can basically only do one WOT pull in the middle of the day and my temps get up to 180... obviously I need some cooling done, because otherwise a 180mm crank pulley is a bit harsh.
