Use upper cyl lube buddy.Originally Posted by YNOT
I've used just about all of em over the years and swear by Morreys for this.
Don't ever use the fuel doctor, my 97 lancer dropped fuel acconmy by at least 20% every time I tried it, 3 tanks and in the bin with that.
One even cause engine ping big time and Morreys cured that the next tank, so when on a good thing.
Sorry can't remember name of ping one but it was on the shelf last time I looked in s/cheap as a kit-drip bottle and oil, fuel saver maybe!
Tried Penrite one also, seamed ok but doesn't have cleaning additives in it, I rang penrite tech to confirm this.
Its alot cheaper than Morreys but I personally like having cleaner fuel system so recon it's worth the extra $.
Actually had in-depth conversation with Penrite tech and told him I'd buy their product over Morreys if it cleaned also, as I swear buy their engine oil. My old MQ L2.8 ran for years on Penrite with stuffed rings, but just kept on going and was the only oil that slowed oil consumption. and I use it in my Gtr and when I reco Gtr engine the mechanic commented to me how good the bearings were and He agreed Penrite oil was the reason.
Any way, not to mention time saved on maintance.
The junk fuel we have to put up with was regularly fowling injectors on Lancer and my Gtr, causing alot of work.
I can now go along time before I worry about dirty injectors etc.
Now I think about it, a little less valve train noise also.
If you decide to use 2St oil I'd use outboard oil as it's far superior to the others, it's engineered better and larger outboard motors are very expensive to repair/replace, not to mention human life.
Hope this helps
