Yes, you should have this serviced every 3 months no matter what based on what you say! Turbos are hard on oil as someone else pointed out. You might change the oil that is in this car after the new turbo is installed. The new oil will dissolve all the crud that you allowed to accumulate by not changing the oil. I would definitely change the oil within 500 miles and see what it looks like.
BTW: Oil seals are more likely to fail with neglected oil so this may have contributed to the turbo problems. I also wonder about valve stem seals. You might have gotten lucky this time but keep up on the oil and other fluids if you wish to keep this car.
Also inspect, clean, or replace the PCV valve. Sludgy oil can plug these and lead to blown seals due to excess crankcase pressures.
Finally got my car back was in the shop 2 weeks. Got a brand new turbo. Everything flushed. New gasket new front axle. It’s driving beautiful thankful all your help. The mechanic said my lack of maintense and oil changes caused all of this.never again!!
Consider this an education on car maintenance discipline.
And we should consider this and education too. This thread should make us pause for a moment before assuming that a thread is a “troll” just because the lack of knowledge inherent in the question seems to us difficult to conceive. I can only image how unbelievable a question by me on poetry or the rules of English would sound. Nobody knowledgeable in those subjects could possibly imagine I could be that ignorant and still write the question.
Thank you mountain bike.I really needed this eye opener,I always put things off until its too late,not just with cars , so this is a good life lesson.The mechanic said if properly maintained these turbos are built to last the life of the car. Are there more reprocussions of going over the oil change so much, or did I save myself by fixing this ? Thanks
By going seriously over the oil change schedule, you subject the engine to coking of the oil, sludging, and reduced life. Especially when the oil is being cooked by a turbo.
You might do an oil change after the first 500 miles or so in case the new oil dissolves the sludge. Also consider synthetic if the manual doesn’t already specify it. Most modern turbo cars now call for synthetic.
Cwat… I will do that after 500!! I do know that much to use synthetic 
thanks though !
