Just to make sure, you did crank the engine and run it for a few minutes to ensure it circulated thru the engine and oil filter, correct?
And did you replace the filter on this oil change?
It is possible that all the old oil did not drain out due to some sludging of the oil or restriction in the oil galley passages. The engine shaking can be due to excessive oil.
You need to drain a little bit to get it to the correct level. Running too much oil over a distance can damage the rear main seals or the piston rings.
Ok, you did everything right. Based upon prior experience and without benefit of inspecting the oil pan, I suspect there is some oil sludge buildup which means that the correct amount of oil put in will show as overfull due to the oil sludge. Drain a bit out to get to the correct level on the oil dipstick in order to prevent excess pressure buildup from the overfull condition
Synthetic is supposed to be less prone to sludging than conventional oil and the 10w30 should be less prone than 20w50. But there are always variables at play - mileage between oil changes, quality of filter, if engine runs hot.
Ok, sounds good and should be fine when you get the oil to the correct level on the diptstick
A little unconventional way of doing an engine flush, but it worked and that is what counts
They sell engine oil flush at parts stores. You buy a can of it and put in with the oil in it. Run it for about 5 minutes and then drain the oil and change the filter. The oil flush loosens and liquefies the sludge so that it will drain
