Sludge in a infinity 2008 infinity EX 35

Maintenance/Repairs
1

Hi ,

I have a sludge problem with this a 2008 infinity EX 35 .

The car was initially stalling and had been in service at the dealership several times .

Error codes were present and they didnt know what the cause was . They replace spark plugs and tried to find a bandaid rather find the cause ,

Now they are claimimg they cant do anything for the sludge issue and blaming it on poor maintenance … the oil was changed ever 3000 . they have the records of this also .

They talked about flushing the engine , but stated it doesnt work

Is this vehicle prone to sludge . Its onlyonly running on 5 cylinders instead of 6 per dealer . .Does everyone have any

suggestions or solutions ?

woul;d appreciate it .

Thanks

Does this engine require synthetic oil and if so did you use it exclusively?

Only the Nissan GT-R requires synthetic oil (0W-40 or 5W-40) in the entire Nissan/Infiniti lineup.

In fact, every single engine in every single vehicle with that one exception calls for 5W-30 oil. That includes their trucks, suv’s, and small cars. Every single one of them.

I Wonder What Prompted Nissan (?) ( Is That Who Makes Infinity ?) To Start Recommending “Nissan Ester Oil” engine oil in some of their 2008 - 2009 engines ?

We should probably only reply to one of these two threads.
This is annoying.
