I think most of you use castrol 10/50 oil. O'Reilly has quart of valvoline oil on sale for 2.49 quart. Quite a bit cheaper then castrol. Is valvoline just as good.

We buy Castrol 20W-50 in 5 quart jugs for our old cars, and it is less expensive than Valvoline, at least at Walmart. It is interesting to note that we buy all of our oil for the shop at retail from Walmart, as they are cheaper than any of the area wholesalers, even in quantity. The rest of our stock is mostly Valvoline for cars and light truck, and Rotella for diesels. We base our choice on how clean an engine is when we take it apart.

I have been using Valvoline Instant Oil Change service for oil change and lube for the past several years for my 53 Club Coupe. They use Valvoline 10W30 detergent oil and I supply the oil filter, since they don't have them in their inventory. I buy the oil filters from Rock Auto which sells WIX metal canister filters, not the cardboard canisters sold by Dennis Carpenter and Mac's. I paid $40 + tax after deducting $10 coupon for the oil change and lube. They also check tire pressures. coolant level, trans and differential fluid levels. You should bring wrench for oil filer canister since they only have metric tools. Also, double check the oil filter installation for proper fit of gasket and tightness of canister lid (the first time I used them, they didn't tighten the canister lid properly, and I drove away with oil leaking from the canister; luckily, I stopped for gas and saw a trail of oil behind my car. I returned and they apologized, fixed the problem and added more oil to the proper level.) Also, be prepared to guide the tech on the location of the grease fittings. They offer frequent coupons and specials on their website. I did my own oil changes in the past, but I had to put car up on jack stands, but 5qt jug of Castrol 20W50 at Walmart, and filter at auto parts store. At my age (80), I decided it was easier to pay for the service. The techs at Valvoline love seeing the "old" cars and always take a picture or 2.

Saving money is good but using the proper motor oil with the correct amounts of ZDDP, phosphorus, zinc and sulphur to protect the wear surfaces of your flat tappet cam and lifters is more important. These ingredients are not present in sufficient quantities in modern motor oils commonly available in auto parts stores or discount houses. If the oil you are using has an API Oil Service Rating of SM or higher, the zinc additive package has been removed to meet current EPA emissions standards. The zinc additive package poisons the catalytic converter shortening its life. Our cars don't have catalytic converters so we don't have to use low or no zinc oils for function, they are forced upon us because they are commonly and economically available. Some of the oil companies offer racing or other high performance oils that do provide some of the required additives but they generally cost twice as much as the common off-the-shelf entry level oils. One way to solve this problem is to use a good quality name brand conventional oil like Pennzoil, Valvoline or Castrol with an additive which provides the correct amounts of the previously mentioned ingredients. Doing this allows you to save money while being able to extend the life of your engine. One additive that provides everything you need is Red Line Engine Oil Break-In Additive. Just follow the instructions on the label for the correct amount to add to your engine at each oil change.

I'm with CARCRAZY. I use Pennzoil HD 10-30 and add Rislone formula zinc etc at their prescribed amount. My engine has no filter. When I change the oil every 1,000 miles it is still relatively clean and very little sludge has been found in the oil pan. I'm 85 and do my own under car maintenance. To the extreme, my modern VW has no oil pan drain and it has to be sucked-out thru the dip stick tube which concerns me re sludge build up. As well, I notice my local Valvoline station also sucks out the old oil out - saves them time and labor - no hoist needed. Not good .... then again they're putting us in the age of disposable cars.
