I am currently using Amsoil 20W50 and it costs me almost $10 a quart. I am now going to be using my car as a daily driver, putting 40 miles roundtrip to my new office, 200 miles a week, therefore I will be using about a quart of oil a week, what's the best oil for the cheapest price?

No joke - do a search for threads by Doug Hillary on the topic. Some diesel supply shops sell it by the gallon much cheaper than Mobile 1.

I run Valvoline VR-1 20W50 non-synthetic at less than $3/quart. Fine on the street, fine on the track.

ive run castrol 20-50 in my cars for along time- well castrol in general. Never seen any crap buildup while working in there. Costs like 3-4 a quart.

How does it compare to Valvoline VR-1 20W50??

xsboost90

ive not used valvoline- when my father used to race offroad vw's he said valvoline would leave deposits and such in the engine after being run hard, but castrol was alway nice and clean and would hold viscosity much better. I personally dont like synthetics and they are expensive.

Thats what i used to use. I think it was SKI or someone here who told me that VR oil was bad and that it left deposits. I looked into it and it was true when i changed the oil. So i switched to castrol and i havent looked back ever since. I use 20-50 i also leaked allot less and cunsumed allot less. BTW if your car consumes all of that oil then there must be somthing wrong . My car has a leak and i only have to put a quart like every 1350 mi or so.

Mobil 1 leaks like most synthetics and it's expensive. I have used 20-50 castrol for a couple of years and see no sludge. I am thinking about moving to 20-50 valvoline because it is a little better refined than castrol.

I guess I'll try out the Castrol (GTX, right?), since it is the same price as the Valvoline, $2.99 a quart. I have an oil leak that comes down the side of the dipstick as well as on the cross over pipe down to the starter and exhaust. I think it is from blow by or something, coming out of the oil pan or rear main seal. I have to put in 2/10's of a quart everytime I take her out to keep her full, it smokes underneath when I floor it, but when I take it easy it leaks less.

He was the one who recommended the VR1 to me a while ago.

A search would show up a lot of threads on this topic, but it is a good topic to continue to revisit as the industry changes.

Time to rebuilt the turbo your getting allot of blow by. I am getting a little bit.

Thats funny so it prob wasnt him. I have also read this some where else.

I use AMSOIL 20w50 Series 2000 racing oil in my 944 Spec Car. Cost is high, but then again it sees alot of hard use.

My street 951 gets Valvoline VR1 20w50 dino oil. I have some oil leaks (drip on the crossover pipe) so I don't want to risk sythetics, but once I fix the leaks it will get probably mobil 1. I will not use the Series 2000 stuff unless it becomes a dedicated track car.

I have the same leak, it is minimal, but still a major pain to put in oil every other day
