Or

http://www.amsoil.com/catalog.aspx?code=AELQT-EA
Mercedes dealer says they change with 5W-30.. can I use Mid-SAPS or should I stick with Low-SAPS 5W-30?
Most of my driving is highway 60 miles highway round trip per day for work.
Thanks

I don't see Amzoil on that list. You might check with them before the investment. It needs to be 0-30 or 5-30 ESP oil
The older diesel can use 229.51 oil but you might be out of luck. The Amzoil 5-40 is on that list.
Since it late Spring , & your diesel engine start-ups are at time when higher temperature will probably be encountered.A safe bet is to match the proper viscosity that is recommended by Mercedes-Benz.60 miles of Highway Driving is different than local Stop & Go driving.
Highway Driving seems to be a positive in the 45-60 miles per hour range.
I recently traveled 8 hours of Highway driving at 45-70 miles driving //..above 60 miles per hour..fuel efficiency was effected...
With the proper synthetic oil ,you will be successful in your travels...

European, USA, & other countries.
There could be warranty issues & all lubricates can be found each specific engine,parts.
Match the specification to the product purchased.
Naturally Mercedes Benz will recommend MOBIL 1 in proper specification
after market filters use is taking a chance, "Knock offs"
Parts like oil filters ,use a Genuine MB oil Filter
The advice being given by other MB WORLD members is sound advice.

I have as yet seen a MB Dealer reach into a box & take out individual containers of Mobil 1 Oil.
They use a 55Gallon drum measure it off.
A Genuine MB Filter is available From a Foreign Parts Supply Store.
I must admit I did my own oil changes at one time but I do not any longer .The DEF , I refill the tank with the right container that attaches ,screws in ,no overflow.
Some individuals purchase PEAK BRAND DEF & proceed using the empty Individual DEF Containers.I have not tried this product.
Short cuts are a money saving but the mechanic needs to be knowledgable.
I no longer use my Original MB Dealer, the mechanic I had "cut corners' Estimate & Service was very poor at premium MB Price.
There are many short cuts but be sure the o-rings are properly installed in the MB oil filter.

If you don't know what you're talking about, please refrain from giving wrong advice on the forums. The MB Bluetec engines all have DPFs and all require ESP olis at a minimum, so MB *APPROVED* 229.51 or preferrably 229.52 spec oils are the only ones you can run without killing your rather expensive exhaust aftertreatment system. And, if you look at the viscosity charts for the GLK 250, unless you live in the middle of the Sahara desert you probably want to stick with a 5W-30 (or again, preferrably) 0W-30 oil. The M1 ESP Formula 5W-30 was actually formulated for gasoline engines (it even says so right on the bottle) despite the ESP and MB 229.51 approval, while the M1 0W-30 (that has both 229.51 & 229.52 approvals) is the best one for the application in the Bluetec GLK 250. This is what the bottle looks like:
If it's not on the MB 229.51 or 229.52 approved list at BeVo AND isn't the proper viscosity, don't put it in your GLK 250. MB 229.52 approved oils don't - can't - exist in a xW-40 viscosity. It's too thick by definition.
The only thing Amsoil has going for it is film shear strength and anti-wear additives. While this is useful in gasoline race engines where the ambient temperatures are always in the "t-shirt" range and the oil only has to last 300 km before you dump it, these same characteristics make it inherrently unsuitable for use in a modern MB diesel enigne. And, don't confuse Amsoil's marketing jargon - "designed for use in engines requiring [insert desired spec] oils" with "has the following BUILDER APPROVALS" [insert desired spec]. Only the second actually means that the oil was approved for use in your enigne. The first is a slimy and underhanded marketing tactic.

A GLK350 ,is a Gasoline engine vehicle as stated.
The direction in the Thread is to give sound advice, Advertisements can have the hype necessary to purchase the AMSOIL Product.
The writer is quite correct to review all specifications...I use the Mobil 1 Product for my Diesel MB GLK 250.
As stated before ,Car owners in Canada, EU or other Foreign Countries may use different blends.The key issue is warranty & emissions..the general rule is to safely say the number model noted on the Mercedes Benz Vehicle can be quite different.
Certain Countries do not require emissions equipment or safety glass.
In the USA, the vehicle is not released to the new owner until the vehicle is in compliance...My MB GLK 250 has run flat tires, the Canadians a compact spare, flat repair kit,compressor & other equipment .
If it's not on the MB 229.51 or 229.52 approved list at BeVo AND isn't the proper viscosity, don't put it in your GLK 250. MB 229.52 approved oils don't - can't - exist in a xW-40 viscosity. It's too thick by definition.

Just for the record - the Canadian ones don't have a compact (or any other kind of) spare - we have a tire sealant kit and a compressor.

I for one am happy that we don't have run-flats like in the US - the ride on those is absolutely HORRIBLE.
The Special spares, carriers etc...
At this time ,the replacement of a 235/50/R-19 MOE Run flat is limited.
Any run flat tire will be expensive , a replacement is 4 tires .
The Stock tire the Dunlop Grandtrek 235/50/R-19 availability can be limited in certain areas...which can answer your question: In the middle of Nowhere replacement??Though the Dunlop may get the driver 40-50 miles , the tire most likely will need replacement if it is a side-wall damage..& extended travel will render the tire not usable,beyond repair...
The Mercedes Dealer probably has the tire at $$$ Mercedes Tire Price.
My best thought will be to repair the puncture far off the road. & get to a tire dealer to remove the tire, patch & plug..."hopefully"
The Dunlop Grandtrek is listed as all-season with the notation "OK to drive in Light Snow" It is not a winter tire & in a snowy region of Canada , don't drive.
I replaced my Dunlop Grandtrek MO tires already with another brand of tire.
Still the size 235/50/R-19 is limited , I put Pirelli's on my MB GLK250 BT...I will stay off the winter roads until clear....use chains ,perhaps...
My selection was a Pirelli PZero MO 235/50/R-19 99W ( Summer Tire)
They have been great but not in Snow at a low temperature...
Maybe in the years to come , more options will be available ,right now everything is fine....If I move to a Snowy area like Maine, Canada, I would need to another set of tires for winter driving. All season tires cannot replace Winter or Studded tires ...My Sister in Maine puts another set of tires for her 4x4 Toyota, her husband does the same on his Toyota 4 Runner..A fact of life....location.location...
I posted the link to the Bevo Mercedes 229.52 list above. Your oil for an OM651 engine needs to be on that list. Anything else is threatening engine abuse and warranty chucking. I've seen our local OReillys Auto carrying the Mobil 1 ESP oil in 0-40 (for gas) 5-30 and 0-30 for gas and the OM651 engine. Walmart will carry it if you bug the customer service folks. Then you pay $34 or so for 5.5 quarts. The oil filter (and oil) is available from Amazon. Search for the best deal in the exact oil you need. The oil filter should be a fleece filter not just paper, the Hengst, Mann and Bosch are all good and OEM. You don't need to use the dealer and their prices unless they match the price.
Sorry for the thread confusion subject mix-up Thread should have been directed to Tires not Oil.
Options concerning proper oil use & specification concerning the right filter .
You have far more experience in the ownership of a 2010 MB GLK350 Class vehicle (Gasoline)& have had experience in problem solving.
Sorry I will delete this forum from my computer just for you .
.. I am 24 years old, but I am use to the slow calm roll of the W123 forum over at benzworld.org nice older people for the most part that don't seem to get their feathers rustled too easily. I have 575 posts in at benzworld.
