yo Mike!

I use 5W-30

Ford recommended 5W-30 though as shown in this;

Oil, SAE Viscosity Recommendation TSB 98-8-16 by Ford for 89-96

APRIL 26, 1999

ISSUE: Ford Motor Company now recommends SAE 5W-30 viscosity grade forservicing any Ford gasoline-powered vehicle regardless of model year.

ACTION: When servicing any Ford gasoline-powered vehicle, use SAE 5W-30 viscosity grade motor oil. Refer to the following text for further details.

Both SAE 10W-30 and SAE 5W-30 viscosity grade motor oils have been recommended in the past depending on vehicle model and model year.

Tests have proven SAE 5W-30 viscosity grade motor oil provides the optimum protection and benefits for Ford gasoline engines. At both high and low ambient temperature conditions, SAE 5W-30 provides the best overall protection. It allows faster starts under cold ambient temperatures.

SAE 5W-30 also provides approximately 1/2% increase in fuel economy over SAE 10W-30.

SAE 5W-30 viscosity grade motor oils certified for gasoline engines by the American Petroleum Institute (API) should be used for all service procedures requiring replacement of the motor oil.

OTHER APPLICABLE ARTICLES: NONE

WARRANTY STATUS: INFORMATION ONLY

OASIS CODES: 401000, 490000, 499000

Then changed it ti 5W-20 in this later TSB

Oil, Application TSB 02-1-9 for 93-96 Source: by Ford via thedieselstop.com

I personally use Penzoil 10W40

All the major brands are good.. I have over 316k on my motor and still going strong on regular oil. It's said that when going to synthetic, you want to do it in the early miles of the motor (under the 50k mark usually)..

RSMike, just swapping out parts can be expensive, but the O2 sensors have approximately 60,000 mile life span, so it was probably a good preventive maintenance thing to do.

Do you know how to pull codes?
