well i'm heading back from germany here very soon and the supra has been sitting for about 3 months. is it ok to fire her right up or do i need to do anything special. i would hate to see my new 7m go to hell.
Change the oil. Then unplug the ignitor crank it a few times then start her up and nothing will happen. Oil is probley broken down already usually happens at 3000 miles or 3 months which ever comes first and seeing its 3 months with no driving change that bad boy.
I let my N/a sit all winter for like 6 months and she started up fine. Ran a little rought from older gas but went to gas station put some new gas in and she ran fine. 3 months is nothing i wouldn't even worry.
put some gas stabilizer in the tank before trying to start. if you didnt change the oil before you left, you may want to do it now. the problem is that the gasoline blowby can make oil acidic and corrode bearings if its dirty and sits for a long time. gasoline molecular chains break down over time too. gasoline has a shelf life of about 16 weeks, from cracking/blending to end usage, not 16 weeks from purchase.
you CAN run it on old gas, but it may gum up injectors and leave alot of residue and varnishes behind, and dirty up the plugs.
welcome back you jerk! you said you were gonna take me to europe with you, thanks for letting me know! i hope you had a good time w/ the ladies and such...
oil stays trapped between the rings, just like its trapped between the bearings. if anything, there may be a lack of oil on the top cylinder. you could put some MMO in the fuel tank since it contains a top cylinder lube.
