I have a Nissan Xterra with the 4.0L that was stored for 4 months.
I pretreated the fuel (3/4s tank) with a bottle of Seafoam as a stabilizer and just in case also used premium (in case of octance decay due to loss of light fractions)..
Also the vehicle has been historically kept very clean in the fuel system (as u would expect of a BITOG member)
But since it had to go via ship had the keep the tank very low .. so it was run down to maybe 1/8th...so surface area was probably high for the fuel
Runs great... started right up after 4 months. topped up with quality non-ethanol gas... and have been doing about half a tank of driving (some of it at moderately high speed) since then.
... but I am worried about the deposits that a decaying fuel might have left.
At my foreign location I do not have access to MMO, Seafoam, BG44k or Techron, but i do have the full line of Gumout, Chemtool and STP products (and a Nissan dealer where I stopped by the other day just to say hello an get some help w/ something minor) , they sell a different product line of NIssans in this country but promised to be able to order any part my exotic, (to them) vehicle may need)
I put in a bottle of STP "complete fuel system cleaner" that has the amine cleaner in it... but my primary concern with aged fuel in the fuel lines is really the deposit of varnish is it not?(?)
Are the amine based cleaners any good at that?
As a Chemist I am skeptical but I am not a fuel chemist so who knows if my thinking is correct.
I believe Chemtool is solvent based rather than detergent based so might think of it as a better choice against varnish but I had a bad experiences with it once (in another Xterra) and my vehicle IS running perfect so I rather not use anything harsh.
Any thoughts to steer me in the right direction?
