My wife just loves the smell of the offical AC Delco washer fluid. I guess it works ok...but she loves the smell so we buy the official stuff.
Pros: pleasant smell, works adequately
AC Delco CR43TS.
Copper plugs are actually the best for performance, precious metals just last far longer.
Pros: best for performance
Cons: shorter lifespan
Part number: CR43TS
I put in ACDelco and surprisingly it lasted till last week (Aug 2024).
Pros: lasted long time
Vehicle:
Mitsubishi Lancer
The AcDelco I installed in 2021 December died this morning so I'd say it's good. It lasted almost 3 years and I only park outside + have a whole sound system + aftermarket horns.
Pros: lasted almost 3 years
Vehicle:
Mitsubishi Lancer
Went with the ACDelco, and it starts great! No grinding or clunking, so it didn't need to be shimmed. Thank you all for the assistance!
Pros: starts great, no grinding
Vehicle:
Mitsubishi
I'd use the original equipment AC Delco plug. Rockauto has them for $6.31 each, with a $3 per plug rebate offered.
Pros: original equipment
Vehicle:
Chevrolet Cruze
Part number: 41-121
Used ACDelco for the first 4 oil changes and then switched to Mobil 1 ESP X2 when RockAuto didn’t have the ACDelco in stock. Haven’t seen a difference.
Pros: no noticeable difference
Don't buy the new blue AC Delco fuel filters TP3018. They changed the o-ring from round to triangular and they won't seal properly. I always get a replace fuel filter warning with them.
Cons: won't seal properly
Part number: TP3018
