Regular Oil vs Synthetic Oil
Good day everyone,
I recently got the oil changed at the dealership for my 2010 XFR and was estonished to find out that the car only takes regular oil. the dealership even told me never to put synthetic oil in the car...
My understanding was that synthetic oil has better operating characteristics then regular and could be used in any 4 stroke motor. Is anyone using synthetic on their 5.0L motors?
thanks

Back in the day, my brother and I raced AMA/AFM Mostly GP2 and Superbike. We were in the habit of rebuilding the 4 stroke bikes every 5-10 races, inspecting parts and putting new piston rings in. Redline was the first synthetic available to us and since they gave it away to racers in those days we gave it a try. The first time we tore down the engine in a yoshima 400-4 we got the surprise of a life time. Virtually no wear on any engine components. We raced that bike for another 2 years and never replaced a single engine component. I've been using synthetic in every vehicle ever since with great results.

How do you do that Lew?..I mean, I know you have a 12 and is under warranty..How do you change oil with other than what Jaguar Recommends without voiding their warranty and do you do it yourself?, Because from what I know, the dealer has the pumps to suck it out as there is no drain plug per se, that will get it all out.....Just curious

There are no 'DOT' specs for engine oil, just brake fluid.
The manual says:
"5W-30 engine oil, meeting Jaguar specification
WSS M2C913-B is preferred"
for the 4.2L engine, and
"Use only 5W-20 engine oil, meeting
specification WSS M2C925-A.
Jaguar recommends:
Castrol SLX Professional OE 5W-20.
In an emergency, if oil of the above
specification is unavailable, the engine can be
topped-up using a maximum of 1 litre (2 US
pints) of 5W-20 oil meeting specification
ILSACGF-4 API SM."
for the 5.0L engine.

sadly enough, quote of a quote on a Land Rover forum:
Guessing Moss Magnusson does not apply as the service is included during warranty. The problem of course, is that the interval is controlled by Jaguar.
A longer version of the quote:
Difference between Ford M2C925-A and M2C930-A - Bob Is The Oil Guy
Another from that Forum - if we use the same engine as the Jag - here is a extract from their training newsletter
· Stable viscosity for sustainable performance
· Improved engine cleanliness and engine protection
· Better ability to compensate for various driving styles
There are several features your new Jaguar customers should know about:
· The new Castrol oil, SLX Professional 5W-20, is the only oil recommended for the new 5.0L AJ V8 engines
· A service reminder in the Message Center lets the driver know when it's time to change oil
· Service Interval is every 15,000 miles or 12 months, whichever occurs first. It's important that your customers visit your Jaguar dealership yearly for annual service
· The first scheduled maintenance service visit is Complimentary
· Maintenance Interval Message automatically appears when it's time for service
· Checking the oil level is simple using the built-in "digital dipstick" on the car's onboard computer. The new engine does not have a traditional dipstick
The Jaguar/Castrol co-engineered 5.0L engine 5W-20 synthetic motor oil is the only lubricant completely tested to be compatible with Jaguar’s new engine components and other fluids and sealants. No substitutions should be made as the warranty coverage requires the use of the proper Jaguar specified lubricant

For Gabriellus; if, in-fact, your dealer tech told you such rubbish then to need to run away from that dealer as far as possible. Go now and get the proper oil put in your car by a reputable service department, independent tech or do it yourself, but do it NOW and then report this joker to Jaguar @ 1-800-452-4827.

read the actual specification
see post #10: meeting specification WSS M2C925-A. Do the research and you will find that oil meeting spec is rare. Use out of spec oil and the warranty is toast.

Redline, Amsoil and Mobil One Extended Performance all claim to meet this standard. Also, Mobil One Extended Performance WSS M2C930-A and WSS M2C945-A meet the standard.

But, the statement being addressed was "any SAE 5W-20 synthetic motor oil will do". Maybe it will, maybe it won't as a matter of physics. But, it will not meet warranty requirements on that basis only. The oil must be recognised as meeting the Jaguar spec WSS M2C925-A, period, full stop. There is no room for confusion if a warranty claim arises.
