First off, this is not a "which oil is better" thread.
Sadly, it IS an oil thread and even after reading the sticky and numerous oil threads I would like to have some clarity before taking the next step.

My car is a 2002 and has had BMW/Castrol 5W-30 all its life . After reading all I could find about the dreaded subject of oil, I have decided to go with the TWS 10-60. My Indy is charging me $135 for oil change which I think is fair enough as I do not wish to deal with used oil disposal.

My question is, for an engine that was broken in on and ran on 5W-30 all its life, are there any adverse issues that can happen from drastically changing oil viscosity to the TWS 10-60?
I am buying into the myth/fact that the S62 should have always been using 10-60 but is it too late at 66K miles to change to 10W60?

I would greatly appreciate your help and input.

First of all: Why are you switching to 10W60? What problems do you have with 5W30 that makes you want to switch to 10W60? Have you done an oil analysis?

Second of all, in answering that first question, here's the mandatory sign...

Diny,

Trust me, I thought long and hard before posting the question, I knew I was asking for it.LOL

I have had an oil analysis and the 5w-30 oil at 2000 miles showed as much wear as the lab folks are used to seeing on oil with 5000 miles. I figured since the engine was designed to run on 10-60 I should make the switch, but I am cautious as the engine from day one has been running on 5w-30.

Diny, that is one funny graphic. Had a great laugh this morning.

I agree with your comment. What would make someone change to 10-60 without cause? In regards to a $135 oil change Ill use a quote from Vincent in Pulp Fiction: "Ill shoot him on general principle, its not the money". That is an outrageous price to change oil.

Good God another oil thread.

2001, 65k miles, I run 5w-30 like it says in my manual and in my car. Oil analysis is perfect. No oil consumption.

5w-30 doesn't ruin engines.

To answer your question, no, simply changing from 5W-30 to 10W-60 will not give you any problems. I might result in some consumption for a short while but it should settled down. But as said before, I don't know why you'd bother. How do you drive the car? How many cold starts? How hard does it get driven? What engine operating temperatures does it typically see? I'd be surprised if anything you said regarding those questions would justify a change to 10W-60. I would keep your money in your wallet.

At the risk of getting slammed for this, I would not jump to the conclusion the engine was 'designed' to use any particular oil viscosity, oil additive packages perhaps, but not viscosity. Your choice of oil viscosity is all about how you operate the car. Manufacturer recommendations are often based on a typical cross section operation of a car for the 3 to 4 year warranty period, after that you're fair game when it comes to repairs. In short, just because a BMW dealer says 10W-60 or it's one of the recommended oils it doesn't mean it's right for you. I for one do not use 10W-60 in my car, its operating conditions don't suit it, I use Mobil 1 0W-40..

Anyway.. as said above.. tonnes of oil threads.. go read some of my previous posts of ignorance :) .. Choose an oil that suits your operating conditions, if someone blanket recommends one to you without asking you questions about how you use the car... slap them.. and walk away.. they know nothing about oil.

Is it really? The oil alone is just over $100.

I switch between TWS 10W-60 (warm half of year) and Mobil1 0W-40 (cold half of year) mainly to prevent cold start wear. No problems so far.

Engine was designed to use 10w60, what I use on 2001.
i think it should be a rule anyone who says this or "10w60 is the only/right oil" must back it up with technical facts other than BMW's recommendation is finally 10W60 only

i think a better term would be they expected the M5 would need a 10w60

That's not the question at hand, Tim. The question is whether switching to 10w60 will do harm to an engine that used 5w30 all of its life.

This one time, at band camp, I used something else besides Edge 10W60 and my engine exploded!

I love oil threads!

Used!? What do you mean used!? You don't have to use something other than TWS to have a problem ya know! I've heard from respectable engine builders and mechanics and BMW dealerships and BMW specialists and respected BMW indepdentents and my dads mate called Steve that if you put a tub of Mobil1 0W-40 in the same garage as the E39 M5 and leave it over night.. it'll probably catch fire and explode :)

How is it not? He asked if "it was too late" to switch to TWS? Implying 5w-30 has damaged his engine. We all know there are so many factors that go hand in hand with this topic. Something as simple as changing oil isn't going to "save" a damaged engine.

Say what you want, I really don't care. Oil opinions are like a-holes, everyone has one and most of the time it's just full of crap. Oil threads are a complete waste of time anymore. This horse had been beat to ***** worse than any other subject.

I'm out.

I apologize if I wasn't clearer. I didnt mean to imply that the engine is/was somehow damaged by 5W30, I was trying to point out that since engine was broken in on 5w30 and ran for all of its life, am I going to have issues like seal pass through or oil consumption by changing the viscosity (thicker vs thinner oil).

Tim, you use 5W30 all the time and now you're having clutch problems. Concidence? I THINK NOT! :deal:

since the engine was new it probably made little difference - now that it has racked up more miles it wouldn't hurt to put 10w60 in - am not against 5w30 but not for intervals longer than 3000 miles or temps above 40F

if you're afraid of going too thick then pick up a XW-40 or XW-50

You haven't read any of my threads have you.......

I removed perfectly good and working clutch to put on an aftermarket unit that won't work. I highly doubt my choice of oil has anything to do with my problems. Then again, at this point I'm not ruling anything out.

But as always I am sure you can't lose this arguement in your mind so it is a mute point. Yup, 5w-30 ruined my clutch.

Good day sir ............
