A PRECISE OIL LEVEL CHECK ON 2004 MG-ZR
The oil level dipsticks which are used on the 200 and ZR are not the best for showing a precise reading, the earlier all plastic one for the 200, in most cases eventually snaps leaving the tip of it floundering in the oil sump after several years of constantly being used. The wire one with plastic tip doesnt fair too much better either, getting smeared when being withdrawn from out of the 'dog leg' shaped dipstick tube, so getting a precise oil level reading is not always going to be possible using this traditional method.
To solve this problem, came up with the idea of using a semi rigid plastic tube, one from an old waxoyl kit was just ideal for this. After the tube has been precisely marked up for a correct depth of insert, including each of the high and low oil level reading marks.
On a 'cold engine' and with the vehicle on level ground, the tube is inserted into dipstick tube, after a few seconds thumb pressure is then applied to hold a vacuum while being withdrawn to give a positive and a much clearer view of the oil level reading as shown.
The MG doesnt use any oil between each of its twice yearly oil and filter changes, so will always show my own preference of a tad just below the maximum mark. this method shown is for intermittent usage. and taken only on a cold engine, After checking the vehicles oil level reading the vehicles original dipstick can then be returned back.
