Yes that is the oils in it. It also has 30w in the shocks but the car bottoms out very very easy. I needed to put spacers in the springs but it makes it bouncy especially on the front and the back bottoms out and lifts the back of the car off the ground. I was going to put 50w all round. The macstar engine is in great condition no play in the conrod and smooth bearings good compression. The best I can get it to go is just a bit too delayed at the bottom mid range and top end is good but I have had it to the eyeballs with poor response so I have a 32 to go in it. Was thinking the 17t clutchbell might be good but having second thoughts due to my 28 being poor low down might go for the 16 or even 15 any info or feedback would be greatfull. I'm thinking of going with 5,000wt in the front 3,000wt in the back but not sure anymore what to do with the middle.
