Great advice. Just completed my first experience at oil and filter change in the roadster. Jacking the whole front of the car up at the same time was the most difficult part. I used a 3 T and a 1 1/2 ton smaller jack to get the front tires about 6 " off the ground. Jack stands fit nicely under the front sway bar. Four screws and off comes the plastic splash pan, exposing the engine drain plug. I let the rgt side down slightly to ensure a more complete drain. Drained the oil, replaced the plug and the splash pan and let the car down. The oil filter housing was marked to be retightened to the same spot. I used a Harley filter wrench (same size) to unscrew the casing and removed the old filter. Re and re the four oil rings and the cartridge. I added 7 1/2 qts of 0-40 bringing oil level to full - to be checked next week. Glad I did not just dump in 8 1/2 qts...cause it would off been overfull. Good advice on stocking your own filter and oil. Lots of people have never heard of 0-40....and the filter is another story. Now to determine the slight oil puffs from the rgt rear of the engine.
