The only concern for a 40 weight is dependent on the bearing clearance, like for example if it was supposed to take a 20 weight or 30 weight maximum but now you are stepping up to a 40 weight there might* (and I emphasize might) be a problem. I have no idea what lotus specs but it should be ok. As long as you don't put 10w60 in there like some people do for the s55.... then you should be fine.



*Pennzoil/quaker state 5W40 is a relatively low viscosity 40 weight (kv100) so it should be fine.

I've lost count on how many beers I owe you, but suffice it to say that if I ever visit there, you're going to be toasted when I leave. haha

I don't understand it enough to know if I can use a 40W instead of a 30W, the internet is insane on the topic. I can't imagine this would be an issue, so that's my plan.

So I'm going to try the Pennzoil platinum euro 5w40/quaker state euro 5w40 in both cars, 2 birds with one stone, unless you say otherwise. Not sure about that 40W, should be fine, right? I'm not racing the car, it's just a fairweather friend.


And THANK YOU both for all the help.

You are welcome.
Here is the thing about European approvals. They are based on HTHS not grade. HTHS is resistance of oil at 150c to permanent or temporary loss of viscosity. LL01, MB229.5, Porsche A40, VW 502.00 oils have minimum requirement of HTHS 3.5cp. That can be achieved with W30, W40 and obviously W50 or W60 oils. However, those approvals also have fuel efficiency requirements. So, you cannot go crazy thickness wise. Most of these oils are heavy XW30 or light XW40. Grades are range. XW30 grade is 9.2cst to 12.4cst. XW40 grade is 12.5 to 16.5cst.
Quaker State/Pennzoil Euro are at the bottom of XW40 grade around 12.9cst. However, when one blends oil you really cannot achieve exactly that cst (KV100) so it is always listed as "typical value). I have seen few days ago VOA (Virgin Oil Analysis) of QS 5W40 and KV100 of 12! Now, VOA usually has higher margin of error than UOA (Used Oil Analysis) so let's say oil was 12.5cst. That is right at W30 border. So absolutely no worries about whether it is too thick. Also, if it is approved by BMW, it is OK.
As for clearances, oil is never really too thick. At KV40, even 0W8 oil will be thicker than 10W60 oil.
As for Exige, Toyota engines can take anything, literally! For example, Toyota recommends for my Sienna 0W20 oil in 2GR-FE engine. In Australia recommendation is 20W50 in some areas.
So, use QS in both cars with confidence.

It's perfect for you since now you'll only have to stock 1 oil, and it's a really fricken good oil at a really fricken good price.

Got an oil change booked this Thurs

I have 4l of Castrol edge titanium 5W-30 LL (does not say LL-01 if this matters?) but not approved BMW on the back is that significant?

My garage will use Fuchs oil which seems to get good rep on BMW and GTR forums from a quick search this morning.

Interestingly on BMW UK s site says I can use 0W-30 or 5W-30 in my car (2016)? Why is that?

Tbh never found what oil to use as confusing as in this car!

This car can use 0w30, 5w30, 0w40, and 5w40 without issue based on bmws list of acceptable oils based on the LL01 criterion. However the grade of oil isn't the issue it's the certifications.

So if you want it to be simple buy an LL01 oil and you're ok.


If you want to use a non LL01 oil it must pass the other stringent oil tests like Porsche A40 and MB 229.5, while not being a high saps blend because that won't be great for a direct injected car.


I have no idea about Fuchs oil or that type of Castrol edge, edy may be able to comment as he knows alot more about oil than me.

[3t3p]

I 'think' this would be ok?

I'd buy another 4l to do full change as think it's 7L a pop?

You are good to go!

[3t3p]

Well actually the garage I used said service not due so didn't change my oil. Don't think they understood I wanted to do it early.

So now I can use that oil if I need to, shall I just order more of the same and take it to a garage? I plan to do oil changes annually.

Cheers

If you have enough oil currently on hand then wait for a sale before stocking up on more.

I’m running this year round in my Stg 2+ E50 setup (445whp/507wftlbs): http://www.redlineoil.com/euro-series-5w40-motor-oil

Hoping it’s robust enough for hot summer track use, flexible enough for winter cold starts (25F is the coldest start it sees), and compatible enough for half pump gas/half E85.

I still need to get Blackstone back on my first change with this oil, but what do you think?

[M Fifty]

So... if you don't park it outside and drive it in Saskatchewan during the winter, why would you not go for a 0W oil - regardless - of the hot viscosity? Not being an ass, but if it likes 0W40 why would you use 5W40 in a modern engine?

In my case, ethanol fuel/oil dilution was causing me to have to add a cpl quarts of oil bn changes when I was using 0W oil. 5W-40 has made that go away.

But, that’s kind of a special use case.

First off why didn't you go for this one instead: https://www.redlineoil.com/5w40-motor-oil

It has a slightly higher hths rating, and is formulate with ll01, Porsche a40, and MB 229.5 specifications in mind, which are more riguourous than the oil you sent me. Now keep in mind these redline oils do not actually have the real OEM approvals they are "suitable" for their use but it is still better that they are designing it around these specs. So I'd go for the oil I linked above instead of the one you linked.


Now noting your extremely high oil temps on track of around 270F and how hard you push it, this oil would be perfect for you. It has the highest hths rating I have ever seen out of a 5w40 oil, and like most redline oils it probably has alot of esters too which helps . So track use should be perfectly fine, likely this oil will give you the best protection.


It also has a pour point of -45C so you're good to go for winter use as well.


With high e85 use you should probably do more oil changes to combat fuel dilution but that should be all. It's a really robust oil as it is so I don't suspect e85 fuel dilution to be too much of a factor, but again edy can better elaborate.



Now here's the caviot I know you have a sport cat and I believe redline oils have alot of zinc so that might not play too well with your cat. Oxidation wise idk how long this thing will last but it should be long enough for yearly oci's. edycol can better comment on this


But overall yeah it's perfect for the track and should be fine for daily year round use.

I picked the Redline Euro 5W-40 since it's thinner than the regular Redline 5W-40, and the HTHS is practically the same (4.3 vs 4.4). I figured that'd be better if I'm trying to run the same oil all year, winter & summer.

And, since I change my oil a couple times a year, I wasn't concerned with it being LL-01 or not.

No idea about the zinc, but the Euro LL-04 version is "supposed" to have higher ZDDP levels than the regular Redline 5W-40. I don't have any data on that, tho.

There are more tests to just durability with ll01, MB and Porsche. But let's see what edy says.

Why the talk of 5W-40?

To blow all the 0W guys’ minds.

I haven’t found a 0W-40 with high enough HTHS for summer track use in my car, and I run half E85 which causes a little oil dilution/thinning so the 5W-40 is about where I need to be.

Previously I used BMW OEM 0W oil until I start tracking hard and running ethanol tunes.

Old post, so who knows if the formulation has changed.

Well that's not technically true, only a UOA can determine that for sure. But there are off the shelf 0w40 oils that can handle track use



But remember Porsche a40 is the test where they drive a car flat out on the nordschliffe for hours and ensure the oil doesn't degrade and the engine doesn't get worn out as a result of that. And oils like PPE 5w40 and motul xcess gen 2 5w40 has an hths of 3.8 and they both have Porsche a40, so they're fine for heavy track use.


Again to be sure you need a UOA, but imo your oil cooler should be good enough to ensure the oil doesn't sheer when running a good 40 weight Porsche a40 certified oil.

True, true.

Since I’ll hit 270F oil temp many times on a track weekend, I filtered my oil search to only those with HTHS >4, but like you said that’s not the end all/be all for track worthiness for my conditions.
