1 . A fuel detergent comprising the reaction product of reacting at least the components (a) a high molecular weight hydroxyaromatic compound, (b) an aldehyde and (c) an amino hydroxy compound.  
   
   
       2 . The fuel detergent of  claim 1 , wherein the components are present in the ratio of 1:1:1, respectively.  
   
   
       3 . The fuel detergent of  claim 1 , wherein the hydroxy aromatic compound is selected from the group consisting of phenols and cresols.  
   
   
       4 . The fuel detergent of  claim 1 , wherein the aldehyde is selected from the group consisting of formaldehyde, acetaldehyde, propionaldehyde, butyraldehyde, valeraldehyde, caproaldehyde, heptaldehyde, and stearaldehyde, benzaldehyde, salicylalidehyde, furfural, thiophene aldehyde, and formaldehyde-producing reagents, where the formaldehyde-producing regent is selected from the group consisting of paraformaldehyde and formalin.  
   
   
       5 . The fuel detergent of  claim 1 , wherein the amino hydroxy compound is selected from the group consisting of a compound containing both (i) at least one primary or secondary amine and (ii) at least one hydroxyl groups.  
   
   
       6 . The fuel detergent of  claim 1 , wherein the high molecular weight hydroxy aromatic compound has a molecular weight greater than 500.  
   
   
       7 . The fuel detergent of  claim 6 , wherein the high molecular weight hydroxy aromatic compound is a PIB-cresol, the PIB-cresol having a molecular weight of about 700 to about 1100.  
   
   
       8 . A fuel comprising the reaction product of  claim 1 .  
   
   
       9 . The fuel of  claim 8 , wherein the use of the additized fuel reduces intake valve deposits relative to use of a fuel without the reaction product.  
   
   
       10 . A fuel additive comprising the reaction product of  claim 1 .  
   
   
       11 . A reaction process comprising 
 adding an alklate to a flask;    providing an aromatic solvent to the flask;    stirring contents of flask under a N 2  blanket, the N 2  set to about 0.1 to 0.2 SCFH;    adding an amine;    adding an aldehyde;    wherein the alkylate, amine and aldehyde are provided in a ratio or about 1:1:1, respectively and wherein the alkylate is a high molecular weight ortho alkyl substituted hydroxyl aromatic.    
   
   
       12 . The process of  claim 11 , further comprising the step of distilling the contents of the flask under a N 2  blanket, the N 2  blanket set to about 0.5 SCFH.  
   
   
       13 . The process of  claim 12 , further comprising the step of providing additional solvent following the step of distillation, the step of adding the additional solvent bringing the resulting composition to about 25% solvent.  
   
   
       14 . The process of  claim 11 , wherein the amine is an amino alcohol, the amino alcohol selected from the group comprising 2-arnino-1,3-propanediol, 3-amino-1,2-propanediol, ethanolamine and diethanolamine.  
   
   
       15 . The process of  claim 11  herein the aldehyde is selected from the group consisting of formaldehyde, acetaldehyde, propionaldehyde, buyraldehyde, valeraldehyde, caproaldehyde, heptaldehyde, and stearaldehyde, benzaldehyde, salicylaldehyde, furfural, thiophene aldehyde, and formaldehyde-producing reagents, where the formaldehyde-producing regent is selected from the group consisting of paraformaldehyde and formalin
